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.
