Once you have the center and range of your data, you can begin to describe its shape. The skew of a dataset is a description of the data’s symmetry.
A dataset with one prominent peak, and similar tails to the left and right is called symmetric. The median and mean of a symmetric dataset are similar.
A histogram with a tail that extends to the right is called a right-skewed dataset. The median of this dataset is less than the mean.
A histogram with one prominent peak to the right, and a tail that extends to the left is called a left-skewed dataset. The median of this dataset is greater than the mean.
