Kurtosisis the measure of tailedness in anormal distribution curve. It can help us find the outliers in a dataset. Based on the shape of the peak and tail, it can beplatykurtic, mesokurtic,orleptokurtic. How to Create a Graph of Skewness and Kurtosis in Excel: 4 Easy Steps We will use...
Excel Function: Excel provides theKURTfunction as a way to calculate the kurtosis of a sampleS, i.e. if R1 contains the data elements inSthen KURT(R1) = the kurtosis ofS. Observation: Thepopulation kurtosisis calculated via the formula You can obtain the population kurtosis by using the Exce...
based on using the Excel worksheet functions SKEW and KURT to calculate the sample skewness and kurtosis values. Since CHISQ.DIST.RT(2.13, 2) = .345 > .05, we conclude there isn’t sufficient evidence to rule out the data coming from a normal population. The JB test can also be perform...
A number of different formulas are used to calculate skewness and kurtosis. This calculator replicates the formulas used in Excel and SPSS. However, it is worth noting that the formula used for kurtosis in these programs actually calculates what is sometimes called "excess kurtosis" - put simply,...

What is kurtosis? Karl Pearson’s formula for the basic kurtosis is: The basic kurtosis starts with the deviations from the average. These deviations are raised to the fourth power and added up. This sum is divided by the number of data points,n, and then divided by the root mean square...
