WebMar 8, 2024 · A normal distribution is without any skewness, as it is symmetrical on both sides. Hence, a curve is regarded as skewed if it is shifted towards the right or the left. Summary Skewness measures the deviation of a random variable’s given distribution from the normal distribution, which is symmetrical on both sides. 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.
