These are two useful metrics for describing the shape o Kurtosis Examples Kurtosis Formulas Kurtosis or Excess Kurtosis? Kurtosis Calculation Example Platykurtic, Mesokurtic and Leptokurtic In statistics, kurtosis refers to the “peakedness” of the distribution for a quantitative variable. What's meant by “peakedness” is best understood from the example histograms shown below. Jul 8, 2024 · Calculate Skewness & Kurtosis in SPSS In statistics, we use skewness and kurtosis to measure the shape of a distribution. In statistics, kurtosis refers to the “peakedness” of a distribution. In this video, I show you how to determine and interpret the SKEWNESS and KURTOSIS of a distribution. A negative skew indicates that the tail is on the left side of the distribution, which extends towards more negative values.

Skewness and kurtosis are essential descriptive statistics used to understand and interpret the distribution of data. Example: How to Calculate Skewness & Kurtosis in SPSS Calculate Skewness and Kurtosis in SPSS, If you’re delving into the world of statistics, you might encounter the concepts of skewness and kurtosis, particularly when analyzing data distribution. Jan 19, 2025 · SPSS (Statistical Package for the Social Sciences) is a powerful software used by researchers and statisticians for data management, analysis, and reporting. If a given distribution has a kurtosis greater than 0, then it tends to produce more outliers than the normal distribution. However, it is worth noting that the formula used for kurtosis in these programs actually calculates what is sometimes called "excess kurtosis" - put simply, the formula includes an adjustment so that a normal distribution has a kurtosis of zero. Apr 26, 2021 · This tutorial explains four different methods for calculating univariate and multivariate skewness and kurtosis in your data: an online calculator that allows the use of Excel, SPSS, and SAS data sets directly as well as text and csv files, an SPSS program, a SAS program, and instructions for STATA.
