We will see how four of the most common … WebbWhy do we calculate skewness? Skewness is a measure of the asymmetry of a distribution. A distribution is asymmetrical when its left and right side are not mirror images. You might want to calculate the skewness of a distribution to: Describe the distribution of a variable alongside other descriptive statistics.

First, let’s create a list of numbers like the one in the previous part: x = [55, 78, 65, 98, 97, 60, 67, 65, 83, 65] To calculate the Fisher-Pearson correlation of skewness, we will need the scipy.stats.kurtosis function: from scipy.stats import kurtosis. WebbCalculate the Skewness and Kurtosis for a given data set in Excel file: Basic Stats 1. Using the Sigma Magic software, the Skewness value is 1.6 and Kurtosis is 2.4 indicating that it is skewed to the right and has a higher peak compared to the normal distribution.
