Question

a dataset is considered right - skewed if:
a. the mean is greater than the median
b. the mode is greater than the mean
c. the median is equal to the mode
d. the mean is less than the median

Explanation:

In a right - skewed dataset, the tail is on the right side. The mean is pulled towards the tail (right side), so it is greater than the median. The mode is the most frequent value (usually on the left side of the distribution). For example, in a distribution of income where a few people have very high incomes (right - skewed), the mean (affected by high values) is greater than the median (middle value).

Answer:

A. The mean is greater than the median
