Answer: Skewness coefficient
The **Skewness coefficient** is the correct answer because it directly measures the asymmetry of a probability distribution. A positive value indicates a distribution with an extended tail on the right, while a negative value signifies a tail extending to the left. A zero value denotes symmetry. - **Mean (B)**: Represents the average value but does not indicate distribution shape. - **Median (A)**: The middle value in a sorted dataset, also not a measure of asymmetry. - **Mode (C)**: The most frequently occurring value, unrelated to distribution skewness. Understanding skewness is crucial for selecting appropriate analytical and modeling techniques.
