NBT AQL Academic and Quantitative Literacy Test — Questions and Answers

Question 1: Investigations in which samples from a general population are studied over time with respect to some phenomenon is termed as

Action research
Outcome research
Questionnaires
Trend studies (Correct answer)

Correct answer: Trend studies

Trend studies involve the investigation of samples from a general population over a period of time to observe and analyze changes in a specific phenomenon. This type of research aims to identify patterns, trends, and developments over time, providing valuable insights into the long-term effects of various factors. By studying a representative sample of the population, researchers can make informed predictions and recommendations based on the observed trends.

Question 2: A line graph shows test scores rising from 65 in January to 82 in June. What is the overall increase in points?

147
82
12
17 (Correct answer)

Correct answer: 17

82 − 65 = 17 points of increase over the period.

Question 3: Which type of graph is most appropriate for showing changes in a variable over time?

Histogram
Pie chart
Scatter plot
Line graph (Correct answer)

Correct answer: Line graph

Line graphs are specifically designed to show trends and changes in a variable over a continuous time period.

Question 4: Which of the following is a method of integrating the findings of prior research studies using statistical procedures?

Meta-analysis (Correct answer)
Content analysis
Grounded theory
Secondary analysis

Correct answer: Meta-analysis

Meta-analysis is a method of integrating the findings of prior research studies using statistical procedures. It involves systematically collecting and analyzing data from multiple studies to draw conclusions about the overall effect or relationship between variables. By combining the results of individual studies, meta-analysis provides a more comprehensive and reliable estimate of the true effect size or relationship. It allows researchers to identify patterns, trends, and inconsistencies across studies, and can help to resolve conflicting or inconclusive findings. Meta-analysis is widely used in various fields of research to synthesize and summarize existing evidence.

Question 5: Which sentence is written in active voice?

The report was being written by the group.
The student submitted the report. (Correct answer)
The report was submitted by the student.
The report had been submitted before the deadline.

Correct answer: The student submitted the report.

In active voice, the subject performs the action ('The student submitted'), making sentences clearer and more direct.

Question 6: Which of the following is NOT related to dealing with extraneous variables in a quantitative research?

Repeated measures
Homogeneity
Randomization
Bracketing (Correct answer)

Correct answer: Bracketing

Bracketing is not related to dealing with extraneous variables in quantitative research. Bracketing is a method used in qualitative research to acknowledge and minimize the researcher's biases and preconceived notions. It involves self-reflection and awareness of the researcher's own beliefs and perspectives. However, when it comes to dealing with extraneous variables in quantitative research, methods such as randomization, repeated measures, homogeneity, and blocking are commonly used to control and minimize their impact on the study's results.

Question 7: Which reading strategy involves previewing headings, subheadings, and visuals before reading in depth?

Scanning
Annotating
Skimming (Correct answer)
Close reading

Correct answer: Skimming

Skimming involves quickly looking over headings, subheadings, and visuals to get a general sense of the text before detailed reading.

Question 8: What does the 'mean' of a data set represent?

The middle value when data is arranged in order
The difference between the largest and smallest values
The arithmetic average, calculated by dividing the sum of all values by the number of values (Correct answer)
The value that appears most frequently in the data

Correct answer: The arithmetic average, calculated by dividing the sum of all values by the number of values

The mean is calculated by adding all values together and dividing by the total count of values, representing the data's arithmetic center.

Question 9: Which of the following best describes a 'supporting detail' in an academic passage?

The author's name and credentials
The opening sentence of the passage
Specific evidence or examples that back up the main idea (Correct answer)
A rhetorical question posed to the reader

Correct answer: Specific evidence or examples that back up the main idea

Supporting details are the specific facts, examples, or reasons the author provides to develop and back up the main idea.

Question 10: Basic principles that are accepted as being true on the basis of logic or reason, without proof or verification is termed as:

Assumptions (Correct answer)
Hypothesis
Constructs
Propositions

Correct answer: Assumptions

Assumptions are basic principles that are accepted as being true without proof or verification. They are beliefs or ideas that are taken for granted and form the basis of reasoning or decision-making. Assumptions are made based on logic or reason and are not necessarily proven to be true. They are often used as starting points in various fields such as science, philosophy, and mathematics, and serve as foundational principles for further exploration or analysis.

Question 11: In how many different ways can the letters of the word 'MATHEMATICS' be arranged so that the vowels always come together?

10080
120960 (Correct answer)
4989600
None of these

Correct answer: 120960

The word 'MATHEMATICS' has 11 letters, including 4 vowels (A, E, A, I). To arrange the letters such that the vowels always come together, we can consider the group of vowels (AEA) as a single entity. This reduces the problem to arranging the 7 entities (M, T, H, M, T, C, S) and the group of vowels (AEA). The number of ways to arrange these entities is 8!, but we need to account for the repeated letters (M and T), so we divide by 2!. The number of ways to arrange the vowels within the group is 4!, but we need to account for the repeated vowels (A), so we divide by 2!. Therefore, the total number of arrangements is (8!/2!) * (4!/2!) = 120960.

Question 12: Which of the following is the LEAST reliable source for an academic research paper?

A government health agency's official website
An anonymous blog post with no cited sources (Correct answer)
A published textbook from a university press
A peer-reviewed journal article

Correct answer: An anonymous blog post with no cited sources

An anonymous blog with no cited sources has no accountability, no editorial oversight, and no verifiability—making it the least reliable source for academic work.

Question 13: A histogram differs from a bar graph in that a histogram:

Shows a trend over time using connected points
Displays parts of a whole as slices
Shows the distribution of continuous data grouped into intervals (Correct answer)
Compares categories using separate bars

Correct answer: Shows the distribution of continuous data grouped into intervals

A histogram groups continuous data into intervals (bins) and shows frequency distribution, whereas a bar graph compares distinct categories.

Question 14: What is an 'annotated bibliography'?

A collection of direct quotations from each source
A bibliography that includes only internet sources
A list of sources sorted by topic rather than author
A list of sources where each citation is followed by a brief summary and evaluation of the source (Correct answer)

Correct answer: A list of sources where each citation is followed by a brief summary and evaluation of the source

An annotated bibliography includes each citation followed by a short paragraph (annotation) that describes and evaluates the source's content, credibility, and relevance.

Question 15: If a store sells apples for $1.25 each and oranges for $0.75 each, how much does it cost to buy 4 apples and 6 oranges?

$8.00
$7.50
$9.50 (Correct answer)
$9.00

Correct answer: $9.50

4 × $1.25 = $5.00 and 6 × $0.75 = $4.50, so the total is $5.00 + $4.50 = $9.50.

Question 16: Which of the following best defines 'inductive reasoning'?

Applying a universal law to a particular situation
Using specific observations to form a general conclusion (Correct answer)
Repeating a claim until it seems true
Accepting an argument because an authority figure stated it

Correct answer: Using specific observations to form a general conclusion

Inductive reasoning moves from specific observations or examples to a broader generalization or theory.

Question 17: When analyzing an argument, 'validity' refers to:

Whether the premises are factually true
Whether the conclusion is popular or widely accepted
Whether the argument is persuasively written
Whether the conclusion logically follows from the premises (Correct answer)

Correct answer: Whether the conclusion logically follows from the premises

Validity is a logical concept: an argument is valid if its conclusion necessarily follows from its premises, regardless of whether those premises are true.

Question 18: What does it mean to 'evaluate the credibility' of a source?

Count the number of references it cites
Check if the source is longer than five pages
Assess the expertise, objectivity, and evidence quality of the source (Correct answer)
Determine whether the source is printed or online

Correct answer: Assess the expertise, objectivity, and evidence quality of the source

Evaluating credibility involves examining the author's qualifications, the objectivity of the content, and the strength of the evidence provided.

Question 19: One pipe can fill a tank three times as fast as another pipe. If together the two pipes can fill the tank in 36 minutes, then the slower pipe alone will be able to fill the tank in:

192 min.
108 min.
81 min.
144 min (Correct answer)

Correct answer: 144 min

The faster pipe fills the tank three times faster than the slower pipe. So, if the slower pipe takes x minutes to fill the tank, the faster pipe will take x/3 minutes. Together, they can fill the tank in 36 minutes. Therefore, the equation becomes x + x/3 = 36. Solving this equation, we find that x = 27. Hence, the slower pipe alone will be able to fill the tank in 27 minutes, which is equal to 144 minutes.

Question 20: What is a 'random sample' and why is it important?

A sample that includes the most extreme values in the population
A sample that mirrors the researcher's expected results
Every member of the population has an equal chance of selection, which reduces bias and improves generalizability (Correct answer)
A sample chosen by the researcher based on convenience

Correct answer: Every member of the population has an equal chance of selection, which reduces bias and improves generalizability

Random sampling ensures every individual has an equal chance of being included, which minimizes selection bias and allows results to be generalized to the broader population.

Question 21: Which reading approach is best when you need to locate a specific date or statistic in a long passage?

Skimming
Annotating
Scanning (Correct answer)
Close reading

Correct answer: Scanning

Scanning involves moving your eyes quickly through the text to find a specific piece of information, such as a number or proper noun.

Question 22: When a question asks about the author's 'tone' in an AQL reading passage, you are being asked to identify:

The vocabulary level of the text
The attitude the author expresses toward the subject (Correct answer)
The structure of the passage's paragraphs
The number of words in the passage

Correct answer: The attitude the author expresses toward the subject

Tone refers to the author's attitude or emotional stance toward the subject, which can range from objective and neutral to critical or enthusiastic.

Question 23: What is 'intellectual property' in the context of academic integrity?

Any information found on the internet, which is free to use without citation
Original creative or intellectual work that belongs to its creator and is protected by law (Correct answer)
Knowledge shared openly in public domain without restrictions
A method of organizing sources in a research paper

Correct answer: Original creative or intellectual work that belongs to its creator and is protected by law

Intellectual property refers to original works of the mind—writing, research, inventions—that are legally protected and require permission or citation to use.

Question 24: A bar graph shows that City A has 40,000 residents and City B has 25,000 residents. How many more residents does City A have than City B?

5,000
65,000
10,000
15,000 (Correct answer)

Correct answer: 15,000

40,000 − 25,000 = 15,000 more residents in City A than City B.

Question 25: If a line graph shows a steep upward slope, what does that indicate about the rate of change?

The variable is decreasing rapidly
The variable is increasing rapidly (Correct answer)
The variable has no meaningful trend
The variable is staying constant

Correct answer: The variable is increasing rapidly

A steep upward slope on a line graph indicates a large, rapid increase in the measured variable over the given time period.

Question 26: A survey of 50 people found 60% prefer Brand A. What is the number of people who prefer Brand A?

30 (Correct answer)
12
60
20

Correct answer: 30

60% of 50 = 0.60 × 50 = 30 people prefer Brand A.

Question 27: A fundamental ethical principle that seeks to prevent harm and exploitation of, to maximize benefits for, study participants is:

Nonmalificence
Justice
Coercion
Beneficence (Correct answer)

Correct answer: Beneficence

Beneficence is the correct answer because it refers to the ethical principle of promoting the well-being and welfare of study participants. It emphasizes the importance of maximizing benefits and minimizing potential harm to participants. This principle ensures that researchers prioritize the best interests of participants and take steps to protect their rights and well-being throughout the study. By upholding the principle of beneficence, researchers strive to create a balance between the potential benefits of the study and any potential risks or harm to participants.

Question 28: A 'false dichotomy' fallacy occurs when:

Only two options are presented as if no other possibilities exist (Correct answer)
A conclusion is drawn from unrelated premises
The same argument is repeated in different words
A popular belief is accepted without question

Correct answer: Only two options are presented as if no other possibilities exist

A false dichotomy (or false dilemma) incorrectly limits the choices to just two when other valid options are actually available.

Question 29: The 'slippery slope' fallacy claims that:

One event will inevitably lead to a chain of negative consequences without sufficient evidence (Correct answer)
An argument is invalid because of the speaker's background
Two unrelated events are causally connected
A popular idea must be correct because many people believe it

Correct answer: One event will inevitably lead to a chain of negative consequences without sufficient evidence

The slippery slope fallacy assumes that a small first step will inevitably lead to extreme consequences, without adequate justification for that chain of events.

Question 30: What does 'audience awareness' mean in academic writing?

Including personal opinions in every paragraph
Writing as long a paper as possible
Avoiding the use of any technical terminology
Tailoring content, tone, and vocabulary to meet the needs and expectations of the intended reader (Correct answer)

Correct answer: Tailoring content, tone, and vocabulary to meet the needs and expectations of the intended reader

Audience awareness means understanding who will read your work and adjusting your language, tone, and level of detail to communicate effectively with that specific audience.

Question 31: What is plagiarism in academic contexts?

Using too many direct quotations in a paper
Writing an essay that is too similar in topic to another student's
Failing to reach the minimum word count
Presenting another person's words, ideas, or work as your own without proper attribution (Correct answer)

Correct answer: Presenting another person's words, ideas, or work as your own without proper attribution

Plagiarism is the unethical act of using someone else's intellectual property—words, ideas, or data—without giving proper credit to the original source.

Question 32: When interpreting a table of data, what is the first step you should take?

Read the title and column/row headings to understand what the data represents (Correct answer)
Compare the largest and smallest values
Calculate the average of all numbers immediately
Identify any outliers in the data

Correct answer: Read the title and column/row headings to understand what the data represents

Reading the title and headings first ensures you understand what is being measured before attempting any calculations or comparisons.

Question 33: If the probability of event A occurring is 0.3, what is the probability that event A does NOT occur?

0.7 (Correct answer)
1.3
0.03
0.3

Correct answer: 0.7

The complement rule states that P(not A) = 1 − P(A) = 1 − 0.3 = 0.7.

Question 34: Two ships are sailing in the sea on the two sides of a lighthouse. The angle of elevation of the top of the lighthouse is observed from the ships are 30º and 45º respectively. If the lighthouse is 100 m high, the distance between the two ships is:

200m
173m
273m (Correct answer)
300m

Correct answer: 273m

The angle of elevation from each ship to the top of the lighthouse allows us to form two right-angled triangles. The height of the lighthouse is the opposite side of both triangles. By using trigonometry, we can determine that the adjacent side of the 30° triangle is (100/tan(30°)) and the adjacent side of the 45° triangle is (100/tan(45°)). The distance between the two ships is the sum of these adjacent sides, which simplifies to 100(√3 + 1). Evaluating this expression gives us 273m.

Question 35: What does 'peer-reviewed' mean in relation to academic journal articles?

The article has been read by at least 100 readers
The article was evaluated and approved by other experts in the field before publication (Correct answer)
The article was written by a group of students
The article was published in a school newspaper

Correct answer: The article was evaluated and approved by other experts in the field before publication

Peer review is a rigorous evaluation process in which other qualified experts in the field assess the accuracy, methodology, and significance of research before it is published.

Question 36: What is the correct use of a semicolon in academic writing?

To separate items in a list when those items contain commas
To introduce a list after a complete sentence
To join two closely related independent clauses without a conjunction
Both B and C (Correct answer)

Correct answer: Both B and C

Semicolons are used to join independent clauses ('I studied; I passed the exam') and to separate list items that already contain commas.

Question 37: What is a 'Boolean operator' in database searching?

A term for searching only within a date range
A type of citation format
A subject heading used in library catalogs
A word like AND, OR, or NOT used to combine or exclude search terms (Correct answer)

Correct answer: A word like AND, OR, or NOT used to combine or exclude search terms

Boolean operators (AND, OR, NOT) are logical connectors used in database and search engine queries to narrow or broaden results.

Question 38: If you flip a fair coin twice, what is the probability of getting heads both times?

1/8
1/4 (Correct answer)
3/4
1/2

Correct answer: 1/4

Each flip has a probability of 1/2; since the flips are independent, multiply: 1/2 × 1/2 = 1/4.

Question 39: In the AQL writing section, which type of evidence is generally considered most credible?

Social media posts
Peer-reviewed research studies or government data (Correct answer)
Personal anecdotes or hearsay
Opinions from anonymous sources

Correct answer: Peer-reviewed research studies or government data

Peer-reviewed research and government data undergo rigorous review and verification, making them the most credible types of evidence for academic arguments.

Question 40: Why is it important to cross-check information across multiple sources?

To verify accuracy and reduce the risk of relying on incorrect or biased information (Correct answer)
To increase the length of the reference list
To comply with a minimum source count requirement
To ensure all sources agree with one another

Correct answer: To verify accuracy and reduce the risk of relying on incorrect or biased information

Cross-checking information across multiple credible sources helps confirm its accuracy and reveals whether a claim is broadly supported or potentially inaccurate.

Question 41: A pie chart shows that 35% of a budget goes to salaries. If the total budget is $200,000, how much is spent on salaries?

$35,000
$70,000 (Correct answer)
$65,000
$140,000

Correct answer: $70,000

35% of $200,000 = 0.35 × 200,000 = $70,000.

Question 42: What does 'citing sources' accomplish in academic writing?

It replaces the need to explain evidence in your own words
It makes the essay longer and more impressive
It gives credit to original authors, allows readers to verify claims, and avoids plagiarism (Correct answer)
It shows the writer has read many books

Correct answer: It gives credit to original authors, allows readers to verify claims, and avoids plagiarism

Citing sources is an ethical requirement that credits original authors, supports the writer's credibility, and enables readers to locate and verify the original material.

Question 43: What is the main purpose of a concluding paragraph in an academic essay?

To introduce new evidence that supports the argument
To restate the thesis, summarize key points, and leave the reader with a final thought (Correct answer)
To ask a series of questions for the reader to answer
To list all the sources cited in the essay

Correct answer: To restate the thesis, summarize key points, and leave the reader with a final thought

A conclusion synthesizes the essay's key arguments, restates the thesis in fresh language, and provides a closing thought or call to action.

Question 44: When should you use an encyclopedia entry as a source in academic research?

Only when no other sources are available
Whenever you need a quotation from an expert
As the main source supporting your central argument
As a starting point for background information, not as a primary citation (Correct answer)

Correct answer: As a starting point for background information, not as a primary citation

Encyclopedia entries are useful for getting a general overview of a topic at the beginning of research but lack the depth and specificity required as primary academic sources.

Question 45: Tickets numbered 1 to 20 are mixed up and then a ticket is drawn at random. What is the probability that the ticket drawn has a number which is a multiple of 3 or 5?

9/20 (Correct answer)
8/15
2/5
1/2

Correct answer: 9/20

The probability that the ticket drawn has a number which is a multiple of 3 or 5 can be calculated by finding the total number of tickets that are multiples of 3 or 5 and dividing it by the total number of tickets. Out of the numbers 1 to 20, there are 6 multiples of 3 (3, 6, 9, 12, 15, 18) and 4 multiples of 5 (5, 10, 15, 20). However, the number 15 is counted twice as it is a multiple of both 3 and 5. Therefore, there are 9 tickets that are multiples of 3 or 5. The total number of tickets is 20. So, the probability is 9/20.

Question 46: Father is aged three times more than his son Ronit. After 8 years, he would be two and a half times of Ronit's age. After a further 8 years, how many times would he be of Ronit's age?

2 times (Correct answer)
2 3/4 times
3 times
2 1/2 times

Correct answer: 2 times

Let's assume Ronit's current age is x. According to the given information, the father's current age is 3x. After 8 years, Ronit's age would be x+8 and the father's age would be 3x+8. It is given that after 8 years, the father would be two and a half times Ronit's age, so we can write the equation 3x+8 = 2.5(x+8). Solving this equation, we get x = 8. Therefore, Ronit's current age is 8 and the father's current age is 24. After a further 8 years, Ronit's age would be 16 and the father's age would be 32, which is exactly 2 times Ronit's age.

Question 47: A graph's y-axis starts at 500 instead of 0. This could be misleading because:

It removes unnecessary whitespace
It shows a more accurate trend line
It exaggerates the visual difference between data points (Correct answer)
It makes the graph easier to read

Correct answer: It exaggerates the visual difference between data points

A truncated axis (not starting at zero) compresses the visual scale and can make small differences appear much larger than they actually are.

Question 48: In a frequency table, the 'relative frequency' of a category is calculated by:

Subtracting the smallest count from the category's count
Multiplying the category's count by the total
Adding up all the frequencies in the table
Dividing the category's count by the total number of observations (Correct answer)

Correct answer: Dividing the category's count by the total number of observations

Relative frequency is the proportion of observations in a category, calculated by dividing that category's frequency by the total number of observations.

Question 49: What is the range of the data set: 14, 22, 7, 31, 19?

31
7
24 (Correct answer)
19

Correct answer: 24

Range = maximum − minimum = 31 − 7 = 24.

Question 50: Which measure of central tendency is most affected by extreme values (outliers)?

Range
Median
Mode
Mean (Correct answer)

Correct answer: Mean

The mean is calculated using all data values, so a single extreme outlier can pull it significantly up or down, making it sensitive to outliers.

Question 51: What is an 'abstract' in an academic journal article?

The full list of references at the end
A footnote explaining technical terms
A brief summary of the article's purpose, methods, results, and conclusions (Correct answer)
The introduction section of the paper

Correct answer: A brief summary of the article's purpose, methods, results, and conclusions

An abstract is a concise summary (typically 150–300 words) placed at the beginning of a research article that outlines the study's key elements.

Question 52: If you roll a fair six-sided die, what is the probability of rolling a number greater than 4?

2/3
1/3 (Correct answer)
1/2
1/6

Correct answer: 1/3

Numbers greater than 4 on a six-sided die are 5 and 6—that's 2 favorable outcomes out of 6 total, giving a probability of 2/6 = 1/3.

Question 53: Which of the following questions helps determine whether a web source is authoritative?

Does the website have an attractive design?
Is the website the first result in a Google search?
Does the website have many links to other pages?
Is the author identified, and do they have relevant credentials or institutional affiliation? (Correct answer)

Correct answer: Is the author identified, and do they have relevant credentials or institutional affiliation?

Authority is established by identifying the author's qualifications and institutional backing, not by the website's visual design or search ranking.

Question 54: What is the 'appeal to authority' fallacy?

Presenting statistics from a government agency
Using expert testimony alongside other evidence
Claiming something is true because an authority figure says so, without other supporting evidence (Correct answer)
Citing peer-reviewed research to support a claim

Correct answer: Claiming something is true because an authority figure says so, without other supporting evidence

The appeal to authority fallacy occurs when someone asserts a claim is true solely because an authority endorses it, without providing independent supporting evidence.

Question 55: What is a 'thesis statement' in an academic essay?

The final sentence of the conclusion
The title of the essay
The central claim or argument that the entire essay supports (Correct answer)
A list of sources used in the paper

Correct answer: The central claim or argument that the entire essay supports

A thesis statement is the central claim or main argument of an essay, typically found near the end of the introduction, that the body paragraphs support.

Question 56: Which of the following is an example of 'circular reasoning'?

'The policy is correct because it is the right policy.' (Correct answer)
'Everyone agrees this is the best approach.'
'We should trust the expert because she has a PhD.'
'Crime rates fell after the new law, so the law caused the decrease.'

Correct answer: 'The policy is correct because it is the right policy.'

Circular reasoning (begging the question) uses the conclusion as its own support, which provides no real justification for the claim.

Question 57: What does it mean to 'evaluate evidence' in the context of the AQL exam?

Focus only on evidence that supports the conclusion
Accept all stated evidence as factually correct
Determine whether the evidence is relevant, sufficient, and reliable (Correct answer)
Count the number of examples provided

Correct answer: Determine whether the evidence is relevant, sufficient, and reliable

Evaluating evidence means judging whether it is relevant to the claim, sufficient in quantity, and reliable in quality and source.

Question 58: Which sentence contains a dangling modifier?

The bell rang as she ran to class.
She ran to class before the bell rang.
Running to class, the bell rang before she arrived. (Correct answer)
Before the bell rang, she rushed to class.

Correct answer: Running to class, the bell rang before she arrived.

In 'Running to class, the bell rang,' the participial phrase 'Running to class' incorrectly modifies 'the bell' rather than 'she.'

Question 59: The term used to indicate the placebo effect in which the knowledge of being included in a study causes people to change their behaviors, thereby obscuring the variable of interest:

Internal validity
Hawthorne effect (Correct answer)
Maturation
Manipulation

Correct answer: Hawthorne effect

The Hawthorne effect refers to the phenomenon where individuals modify their behavior simply because they are aware that they are being observed or included in a study. This change in behavior can often obscure the true variable of interest being studied, as the participants may alter their actions to align with what they believe the researchers want to see. This effect highlights the importance of considering the impact of participant awareness and reactivity when conducting research.

Question 60: What is the 'hasty generalization' fallacy?

Attacking the source rather than the argument
Presenting only two choices when more exist
Drawing a broad conclusion from a small or unrepresentative sample (Correct answer)
Repeating the conclusion as a premise

Correct answer: Drawing a broad conclusion from a small or unrepresentative sample

A hasty generalization occurs when a general rule is derived from too few examples or a biased sample, making the conclusion unreliable.

Question 61: What is the absolute value of -15?

0
-15
-1/15
15 (Correct answer)

Correct answer: 15

Absolute value measures a number's distance from zero on the number line, so |-15| = 15.

Question 62: What is the purpose of a 'hook' at the beginning of an academic essay?

To provide a detailed outline of the essay
To state all the supporting evidence upfront
To grab the reader's attention and encourage them to continue reading (Correct answer)
To define every key term used in the paper

Correct answer: To grab the reader's attention and encourage them to continue reading

A hook is an engaging opening—such as a question, quote, or surprising fact—designed to capture the reader's interest from the start.

Question 63: A data set has values: 4, 4, 5, 7, 9, 9, 9. What is the mode?

9 (Correct answer)
4
7
6.71

Correct answer: 9

The mode is the value that appears most frequently in the data; 9 appears three times, more than any other value.

Question 64: The 'straw man' fallacy involves:

Drawing conclusions from a small sample size
Misrepresenting an opponent's argument to make it easier to refute (Correct answer)
Using statistics incorrectly to mislead
Assuming two events are related because they occurred together

Correct answer: Misrepresenting an opponent's argument to make it easier to refute

The straw man fallacy creates a distorted or weakened version of someone's argument and then attacks that distortion instead of the actual position.

Question 65: Solve the inequality: 2x + 5 > 11

x < 3
x > 3 (Correct answer)
x < 8
x > 8

Correct answer: x > 3

Subtracting 5 from both sides gives 2x > 6, and dividing by 2 gives x > 3.

Question 66: What does a 'sample' represent in statistical research?

A subset of the population selected for study (Correct answer)
The margin of error in a survey
The result of a statistical test

36
48 (Correct answer)
42
56

Correct answer: 48

Each term is multiplied by 2 to get the next term, so 24 × 2 = 48.

Question 92: A double bar graph is most useful for:

Showing the percentage composition of a whole
Displaying a single variable's trend over time
Depicting the frequency of intervals in a data set
Comparing two data sets across the same categories (Correct answer)

Question 99: Which of the following data collection method has better subjectivity?

Questionnaires
Self-reports
Biophysiologic measures (Correct answer)
Observation

Correct answer: Biophysiologic measures

Biophysiologic measures have better subjectivity compared to the other data collection methods listed. This is because biophysiologic measures involve collecting data directly from the body, such as heart rate, blood pressure, or brain activity. These measures provide objective and accurate information about the physiological state of the subject, without relying on subjective interpretation or self-reporting biases. In contrast, self-reports, observation, and questionnaires are more susceptible to subjective biases and may be influenced by individual perceptions, memory, or social desirability.

Question 100: What is 'unity' in a paragraph?

All sentences in the paragraph are the same length
The paragraph begins and ends with a quotation
The paragraph has exactly five sentences
Every sentence in the paragraph relates directly to and supports the topic sentence (Correct answer)

Question 101: What is the difference between 'affect' and 'effect'?

They are interchangeable in academic writing
'Affect' is a noun and 'effect' is a verb
'Affect' applies only to emotions while 'effect' applies to physical outcomes
'Affect' is usually a verb meaning to influence; 'effect' is usually a noun meaning the result (Correct answer)

Correct answer: 'Affect' is usually a verb meaning to influence; 'effect' is usually a noun meaning the result

'Affect' is typically used as a verb ('stress affects performance') while 'effect' is typically a noun ('the effect of stress on performance').

Question 102: X and Y can do a piece of work in 20 days and 12 days respectively. X started the work alone and then after 4 days, Y joined him till the completion of the work. How long did the work last?

20 days
15 days
10 days (Correct answer)
6 days

Correct answer: 10 days

X can do 1/20th of the work in one day, and Y can do 1/12th of the work in one day. After 4 days, X has completed 4/20th or 1/5th of the work. So, the remaining work is 4/5th. When X and Y work together, their combined rate is 1/20 + 1/12 = 8/60 = 2/15th of the work per day. To complete the remaining 4/5th of the work, it will take 4/5 ÷ (2/15) = 6 days. Therefore, the total duration of work is 4 days + 6 days = 10 days.

Question 103: In critical thinking, 'synthesis' involves:

Restating only one source's argument
Listing facts without interpreting them
Identifying errors in a single argument
Combining information from multiple sources to form a new, integrated understanding (Correct answer)

Correct answer: Combining information from multiple sources to form a new, integrated understanding

Synthesis is the process of combining ideas and information from multiple sources to create a new, unified perspective or argument.

Question 104: Which element is essential for an argument to be considered 'sound'?

The argument must be supported by at least five sources
The argument must include emotional appeals
The argument must be both valid and have true premises (Correct answer)
The argument must be long and detailed

Correct answer: The argument must be both valid and have true premises

A sound argument is both logically valid (the conclusion follows from the premises) and has premises that are actually true.

Question 105: When a plot is sold for Rs. 18,700, the owner loses 15%. At what price must that plot be sold in order to gain 15%?

Rs. 22,500
Rs. 25,800
Rs. 21,000
Rs. 25,300 (Correct answer)

Correct answer: Rs. 25,300

If the owner loses 15% when selling the plot for Rs. 18,700, it means that the selling price is only 85% of the original price. To calculate the original price, we can divide Rs. 18,700 by 0.85. This gives us approximately Rs. 22,000. To gain 15% on this original price, we need to add 15% of Rs. 22,000 to the original price. 15% of Rs. 22,000 is Rs. 3,300. Adding this to Rs. 22,000 gives us Rs. 25,300. Therefore, the plot must be sold for Rs. 25,300 in order to gain 15%.

Question 106: Which of the following is TRUE about features of quasi-experimental research design?

Manipulation. control group, randomization
No manipulation of independent variable
Use of correlational approach
Manipulation, but no control group or randomization (Correct answer)

Correct answer: Manipulation, but no control group or randomization

This answer is true because a quasi-experimental research design involves manipulation of the independent variable, but does not have a control group or randomization. In a quasi-experimental design, the researcher cannot randomly assign participants to groups, so they have limited control over the variables. However, they can still manipulate the independent variable to observe its effects on the dependent variable. Without a control group or randomization, it is difficult to establish a cause-and-effect relationship between the variables.

Question 107: Which citation style is most commonly required in social science courses?

APA (American Psychological Association) (Correct answer)
IEEE
Chicago/Turabian
MLA (Modern Language Association)

Question 111: When should you use a direct quotation rather than a paraphrase?

To avoid the difficulty of restating ideas
When the source is longer than one page
Whenever you reference another source
When the original wording is particularly powerful, precise, or distinctive (Correct answer)

Correct answer: When the original wording is particularly powerful, precise, or distinctive

Direct quotations are best used when the exact wording of the source is important for its precision, rhetorical effect, or authority.

Question 112: What is the difference between 'correlation' and 'causation'?

Correlation requires an experiment; causation can be shown from observational data
Correlation and causation are interchangeable terms in statistics
Correlation shows two variables move together; causation means one variable directly causes the other (Correct answer)
Causation means two variables are observed together; correlation means one causes the other

Correct answer: Correlation shows two variables move together; causation means one variable directly causes the other

Correlation means two variables tend to change together, but causation requires evidence that one variable directly produces a change in the other.

Question 113: Which of the following is true about negative exponents?

x⁻² = -x²
x⁻² = -1/x²
x⁻² = x²
x⁻² = 1/x² (Correct answer)

Correct answer: x⁻² = 1/x²

A negative exponent indicates the reciprocal: x⁻² = 1/x², meaning the base is moved to the denominator and the exponent becomes positive.

Question 114: Which of the following is considered as a threat to internal validity of a research?

The Hawthorne effect
Novelty effect
Maturation (Correct answer)
Experimenter effects

Correct answer: Maturation

Maturation refers to the changes that occur naturally over time in the participants of a study, which can potentially influence the results. These changes could be due to physical, psychological, or social factors that are unrelated to the independent variable being studied. Maturation is considered a threat to internal validity because it can confound the results by causing changes in the dependent variable that are not actually caused by the independent variable. This can make it difficult to determine if the observed effects are truly a result of the manipulation or simply due to natural maturation processes.

Question 115: Which of the following is an example of a fact rather than an opinion?

This policy is the best solution to climate change.
Reading is more important than writing.
Americans should eat more vegetables.
The US population exceeded 330 million in 2020. (Correct answer)

Correct answer: The US population exceeded 330 million in 2020.

Question 116: What does 'objectivity' mean in academic analysis?

Using emotional language to persuade the reader
Avoiding the use of data or statistics
Presenting information based on evidence without personal bias (Correct answer)
Only including information that supports the author's view

Correct answer: Presenting information based on evidence without personal bias

Objectivity means relying on verifiable evidence and reasoning rather than personal feelings or biases when presenting or analyzing information.

Question 117: The extent to which it is possible to make an inference that the independent variable is truly influencing the dependent variable and relationship is not spurious, refers to:

Reliability
Internal Validity (Correct answer)
External validity
Internal consistency

Correct answer: Internal Validity

Internal validity refers to the extent to which a study can confidently attribute the observed effects to the independent variable, rather than to confounding factors or chance. It ensures that the relationship between the independent and dependent variables is not due to any other extraneous variables. In other words, internal validity ensures that the observed effects are genuine and not a result of random or spurious relationships.

Question 118: If a rectangle has a length of 9 cm and a width of 5 cm, what is the area?

28 cm²
40 cm²
45 cm² (Correct answer)

Question 120: Find a positive number which when increased by 17 is equal to 60 times the reciprocal of the number.

12
10
17
3 (Correct answer)

Correct answer: 3

The correct answer is 3. To find the number, let's assume it as x. According to the given information, when the number is increased by 17, it becomes equal to 60 times the reciprocal of the number. Mathematically, this can be represented as x + 17 = 60 * (1/x). Simplifying this equation, we get x^2 + 17x - 60 = 0. Factoring this quadratic equation, we get (x + 20)(x - 3) = 0. Therefore, the possible values for x are -20 and 3. Since we are looking for a positive number, the correct answer is 3.

Question 121: What is the greatest common factor (GCF) of 36 and 48?
