# Skewed Distribution

Skewed distribution is a statistical term that measures “asymmetry” (lack of similarity) in a “bell curve” (the bell-shaped graph that occurs when plotting data based on normal meaured traits).

In “normal distribution” there should be a roughly equal number of occurrences of a measured trait on both sides of the mid-point of the bell curve.

The “skewness” (percent of difference) statistic measures how great a change there is in the number of trait occurrences on either side of the mid-point of the curve.
