Which of the following best describes data gathered from two distinct variables?
Explanation:
Bivariate data were obtained from two different and distinct variables (e.g., x and y). Comparative tables, scatter plots, bar charts, and best fits of linear regression can all be used to illustrate and visualize bivariate data.
What instrument frequently gauges potentially dangerous noise levels in industrial settings?
Explanation:
An instrument that is frequently used to gauge potentially dangerous noise levels in industrial environments is the noise dosimeter. It is typically used in a way that constantly processes noise levels during a shift (in a specific work area) and then outputs an equal cumulative number at the end of that shift, representing the worker's potential total noise exposure in that area.
Which of the following DOES NOT typically indicate that a spill may be causing a chemical reaction?
Explanation:
Hazardous substance spills frequently lead to a deadly chemical reaction that follows. Such responses often result in the production or buildup of heat, bubbling, the release of smoke and fumes, odd aromas, and splashing.
Which of the following palettes of colors is used to mark hazardous materials according to NFPA 704?
Explanation:
The NFPA 704 Diamond System uses four colors: yellow (the right side of the diamond, representing the amount of instability), blue (the left side of the diamond, meaning the level of health hazard), red (the top side of the diamond, representing the level of a fire hazard), and white (bottom side of the diamond, depicting individual hazard levels for oxidizers and water reactions). Each section has a number from 0 to 4 representing the hazard amount (with 0 being the lowest and four being the highest).
Which waste code designation numbers should a waste storage container with sulfuric acid from used batteries have?
Explanation:
Strong corrosives (such as acids) would fall under this categorization; per 40 CFR 261, corrosivity (code #D002) is a specified hazardous waste material characteristic to which the U.S. Environmental Protection Agency applies an ordinal waste code value. Toxicology (codes #D004–#D043), reactivity (code #D003), and ignitability (code #D001) are the additional characteristics that fall under 40 CFR 261.
Which of the following illustrated tools most closely resembles a bar graph?
Explanation:
A bar graph and a histogram are most similar. Rectangular bars are ideal for specific rising (or expanding) axis values representing a certain measured quantity or value. In essence, a histogram is a particular kind of bar graph that shows the distribution of numerical data (probability) for a continuous variable.
