WebPearson Mode Skewness. Pearson mode skewness, also called Pearson’s first coefficient of skewness, is a way to figure out the skewness of a distribution. The mean, mode and median can be used to figure out if you have a positively or negatively skewed distribution. If the mean is greater than the mode, the distribution is positively skewed. WebThe mean and the median both reflect the skewing, but the mean reflects it more so. The histogram for the data: 67777888910, is also not symmetrical. It is skewed to the right. …
