What are the three types of skewness?

The three types of skewness are:

  • Right skew (also called positive skew). A right-skewed distribution is longer on the right side of its peak than on its left.
  • Left skew (also called negative skew). A left-skewed distribution is longer on the left side of its peak than on its right.
  • Zero skew. it is symmetrical and its left and right sides are mirror images.
