Question

1. mean and median the figure below displays two density curves, each with three points marked. at which of these points on each curve do the mean and the median fall?

Explanation:

Step1: Recall mean - median property for skewed data

For right - skewed data (a), mean is pulled to the right of median. So in (a), median is at A and mean is at C.

Step2: Recall mean - median property for symmetric data

For symmetric data (b), mean = median. So in (b), both are at B.

Answer:

(a) Median at A, Mean at C; (b) Mean and Median at B
