WitrynaIn statistics, skewness is a measure of the asymmetry of the probability distribution of a random variable about its mean. In other words, skewness tells you the amount and direction of skew (departure from horizontal symmetry). The skewness value can be positive or negative, or even undefined. export search results excelWitrynaThe normal distribution has skewness = 0. So observing substantial skewness in some sample data suggests that the normality assumption is violated. Such violations of normality are no problem for large sample sizes -say N > 20 or 25 or so. In this case, most tests are robust against such violations.
