![]() However, other distributions don’t have zero skew. ![]() Other examples of zero-skewed distributions are the T Distribution, the uniform distribution and the Laplace distribution. A standard normal distribution is perfectly symmetrical and has zero skew. Actually, it’s more correct to describe it as a measure of lack of symmetry. Skewness is a measure of symmetry in a distribution. This second part delves into the mathematics for various types of distributions you’re likely to see in elementary stats. You also learned how the mean and median are affected by skewness. In the first part of this article, we covered the basics for left-skewed and right-skewed distributions.
