What does skewness mean in statistics?
In probability theory and statistics, skewness is a measure of the asymmetry of the probability distribution of a real-valued random variable about its mean. The skewness value can be positive, zero, negative, or undefined.
May 3, 2022 · How to Interpret Skewness. The value for skewness can range from negative infinity to positive infinity. Here’s how to interpret skewness values: A negative value for skewness indicates that the tail is on the left side of the distribution, which extends towards more negative values.
What is a Skewed Distribution? A skewed distribution occurs when one tail is longer than the other. Skewness defines the asymmetry of a distribution. Unlike the familiar normal distribution with its bell-shaped curve, these distributions are asymmetric.

Jul 2, 2019 · Sets of data that are not symmetric are said to be asymmetric. The measure of how asymmetric a distribution can be is called skewness. The mean, median and mode are all measures of the center of a set of data. The skewness of the data can be determined by how these quantities are related to one another.
