A skewed distribution occurs when one tail is longer than the other. Skewness defines the asymmetry of a distribution. Unlike the familiar normal distribution with its bell-shaped curve, these distributions are asymmetric. The two halves of the distribution are not mirror images because the data ar...
The normal distribution is the easiest distribution to work with in order to gain an understanding about statistics. Real life distributions are usually skewed. Too much skewness, and many statistical techniques don’t work. As a result, advanced mathematical techniques including logarithms and quantile...

In statistics, a negatively skewed (also known as left-skewed) distribution is a type of distribution in which more values are concentrated on the right side (tail) of the distribution graph while the left tail of the distribution graph is longer. While normal distribution is the most commonly...

Studying statistics? Then you've likely heard the phrase "normal distribution" when describing data.But what about the phrase "skewed right"? What does a right-skewed histogram look like?And what causes it? In this article, we give you examples of histograms skewed to the right and explain ...
Skewed data is data that creates a skewed, asymmetrical statistical distribution, instead of following a Gaussian (normal) distribution. A skewed distribution on a graph has a curve distorted to the left or right of the graph’s center.

Examples include (a) intrahost adaptation (a selective process) and (b) interhost transmission (a demographic process). The tree in (a) characterizes, for example, neuraminidase (NA) or hemagglutinin (HA) evolution in the influenza A virus, driven by positive selection; selection by host ...
