What can be inferred from a skewed distribution regarding its mean and median?

• A. The mean and median are always equal
• B. The mean is typically greater than the median in right-skewed distributions
• C. The median is always higher than the mean in left-skewed distributions
• D. The mean has no relevance in skewed distributions

Answer: (B)

In a right-skewed distribution, the tail on the right side of the distribution is longer or fatter than the left side. This results in a situation where a few higher values pull the mean upward, making it larger than the median. The median, being the middle value, is less affected by outliers and extreme values than the mean. Hence, in right-skewed distributions, it is typical for the mean to be greater than the median. Understanding the characteristics of skewed distributions is important in statistics. In a left-skewed distribution, the opposite occurs, and the tail is longer on the left side, pulling the mean down below the median. The relationship between mean and median in skewed distributions gives valuable insight into the data's tendencies and potential outliers. Therefore, option B accurately describes this relationship.
