WebDec 16, 2024 · Skewed distribution is when data isn't distributed symmetrically to the left and right sides of the median on a bell curve. It leans either to the left or the right side of the scale, resulting in a non-symmetrical curve. If the bell curve is shifted to the right or the left, the distribution can be called skewed. WebIn probability theory and statistics, skewness is a measure of the asymmetry of the probability distribution of a real-valued random variable about its mean.
