Which distribution has a tail extending to the right, indicating positive skewness?

• A. Right-skewed Distribution
• B. Negatively Skewed Distribution
• C. Symmetric Distribution
• D. Positively Skewed Distribution

Answer: (D)

A distribution with a tail extending to the right is described as positively skewed. In this shape, most data cluster on the left, while a few unusually high values pull the tail toward the right. This rightward tail indicates that extreme positive values dominate the tail, often causing the mean to exceed the median. A negatively skewed distribution would have a longer left tail, and a symmetric distribution would have tails of equal length on both sides. The term right-skewed is used interchangeably with positively skewed, but the essential idea is the rightward tail signaling positive skewness.
