Skew on a histogram
WebbSkewness – Skewness measures the degree and direction of asymmetry. A symmetric distribution such as a normal distribution has a skewness of 0, and a distribution that is skewed to the left, e.g. when the mean is less than the median, has a negative skewness. o. Kurtosis – Kurtosis is a measure of the heaviness of the tails of a distribution. Webb28 nov. 2024 · Histograms .
