WebbA 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 are not distributed equally on both sides of the ... Webb16 juni 2024 · This adjusted moment is what we call skewness. It helps us measure the asymmetry in the data. Perfectly symmetrical data would have a skewness value of 0. A negative skewness value implies that a distribution has its tail on the left side of the distribution, while a positive skewness value has its tail on the on the right side of the …
