Question

select the correct answer. which statement is true? a. the mean lies to the right of the median for a positively skewed distribution. b. the mean lies to the left of the median for a positively skewed distribution. c. the mean lies to the left of the median for a symmetric distribution. d. a distribution skewed to the right is said to be negatively skewed. e. a distribution skewed to the left is said to be positively skewed.

Explanation:

In a positively - skewed distribution, the tail of the distribution is longer on the right - hand side. The mean is pulled in the direction of the tail. So, the mean lies to the right of the median in a positively skewed distribution. In a symmetric distribution, the mean and median are equal. A right - skewed distribution is positively skewed and a left - skewed distribution is negatively skewed.

Answer:

A. The mean lies to the right of the median for a positively skewed distribution.
