Skewness In Statistics. Division by standard deviation enables the relative comparison among distributions on the same standard scale. Skewness is a measure of the asymmetry of a data distribution.
The distribution on the left is symmetrically distributed it is not skewed to either side. Skewness quick introduction examples formulas by ruben geert van den berg under statistics a z skewness is a number that indicates to what extent a variable is asymmetrically distributed. Data that are skewed to the right have a long tail that extends to the right.
Generally if the distribution of data is skewed to the left the mean is less than the median which is often less than the mode.

Compare the data distributions below which we also examined briefly in a previous lesson. Generally if the distribution of data is skewed to the left the mean is less than the median which is often less than the mode.
