Question

the mean of a distribution is 217, while the median is 291. which of these statements is true about the distribution?


A. it is negatively skewed

B. it is positively skewed

C. it is symmetrical.

D.it is the same throughout

Answer 1

You actually can't tell from the information given (in general)

However, they probably mean this: if the median is larger than the mean, then the distribution is negatively skewed.

Answer 2

A.

Answer 3

If the mean of a distribution is 217, while the median is 291, this tells us that half the data lies to the left of 291 and half to the right. For the mean to be smaller than the median, the data set would have to contain outliers lying to the left of the median. This confirms that both J-W and A-Champ are correct; the distribution is negatively skewed.
