Question

what can you conclude?
a. height is more variable than weight.

b. weight is more variable than height.

Explanation:

To determine which is more variable (height or weight), we typically use measures of variability like standard deviation or coefficient of variation (CV). CV normalizes standard deviation by mean (\(CV = \frac{\text{Standard Deviation}}{\text{Mean}} \times 100\)). Weight often has a higher CV than height (e.g., height mean ~170 cm, SD ~7 cm; weight mean ~70 kg, SD ~10 kg – CV for height ~4.1%, weight ~14.3%). So weight’s variability relative to its mean is higher.

Answer:

B. Weight is more variable than height.
