Question

shows the distributions of prices for packs of adult of kid socks at a store. which measure of center is the best to use to compare the prices of kid socks and adult socks? standard deviation mean median

Explanation:

To determine the best measure of center for comparing kid and adult sock prices, we analyze the options:

• Standard deviation measures spread (variability), not center, so it’s incorrect.
• Mean is sensitive to skewness/outliers. From the histogram, adult socks have a price range (e.g., $14–$16) that may skew the mean, while kid socks do not.
• Median is resistant to skewness/outliers and better represents the “middle” of a distribution, especially when data is skewed (as adult sock prices appear to be, with a tail at higher prices).

Answer:

median
