Question 1
Which variable is numerical?
Correct Answer: D
Rationale: Numerical variables are measurable on a numeric scale, while the others are categorical. Skin temperature is measured in degrees, making it numerical. Food group, diet type, and screen color are categories without inherent numeric value.

Question 2
Which variable is quantitative?
Correct Answer: D
Rationale: Quantitative variables have numeric values with meaningful magnitudes, while the others are qualitative categories. Body weight is measured numerically (e.g., in pounds or kilograms). Species, political affiliation, and food group are labels or categories without numeric meaning.

Question 3
Which variable is qualitative?
Correct Answer: D
Rationale: Qualitative variables describe categories or qualities without numeric measurement, while the others are quantitative. Diet type (e.g., vegan, omnivore) is categorical. Volume, time, and interest rate are measured numerically.

Question 4
A student is conducting research on the study habits of fellow students at a college. Which variable of the study is quantitative?
Correct Answer: B
Rationale: Quantitative variables are numeric and measurable. Course load in credit hours is a number (e.g., 12, 15). Type of residence, major, and time of day are categorical descriptions.

Question 5
A student is conducting research on the study habits of fellow students at a college. Which variable of the study is qualitative?
Correct Answer: B
Rationale: Qualitative variables are categorical and non-numeric. Type of residence (e.g., dorm, off-campus) is a category. Time spent studying, course load, and GPA are all numeric measurements.
