Symmetric frequency distribution

WebA symmetric distribution is a type of distribution where the left side of the distribution mirrors the right side. A symmetric distribution is never skewed . The normal distribution is symmetric. It is also a unimodal distribution … WebSymmetry is any operation that leaves the system unchanged. In the case of a probability distribution this could be translated to any operation X → X ′ that returns the same probability P ( X) = P ( X ′). In the simple case of the first example you are referring to the reflection symmetry about the maximum.
