question
a sprinter keeps track of how long it takes her to run the 200-meter dash. what is the level of measurement of the data?
select the correct answer below:
○ nominal
○ ordinal
○ interval
○ ratio

Explanation:

Ratio level measurement has a true zero point, allows meaningful comparisons of magnitudes, and supports all arithmetic operations. Time to run a 200-meter dash has a true zero (0 seconds means no time elapsed), and differences/ratios (e.g., one time being twice as long as another) are meaningful. Nominal data is categorical with no order, ordinal has ordered categories but no consistent intervals, and interval has no true zero.

Answer:

ratio
