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. The skewness value can be positive, zero, negative, or undefined. For a unimodal distribution, negative skew commonly indicates that the tail is on the left side of the distribution, and positive … WebThe arithmetic mean of a series of values x 1, x 2, ..., x n is often denoted by placing an "overbar" over the symbol, e.g. ¯, pronounced "x bar".
