TUTORIAL STATA : UJI FRIEDMAN STATA ➡️ UJI BEDA TIGA KELOMPOK BERPASANGAN STATA

The Friedman Test in Stata In this video, I explain and demonstrate how to perform the repeated measures ANOVA test using Stata. Stata is a statistical software program designed for analyzing statistical data. The Friedman test in Stata is classified as a multivariate analysis. The Friedman test is used to determine the differences between three groups of paired data. Therefore, it is also called the paired three-group difference test or paired three-group comparison test. The Friedman test in Stata is a development of the Wilcoxon test, differing in the number of data groups used. The Wilcoxon test uses two groups of paired data, while the Friedman test uses three groups of paired data. The Friedman test in Stata is classified as a non-parametric statistic, meaning the data used must not be normally distributed. Watch this video until the end; I guarantee you'll be able to do it. Hope this is helpful, friends! #Friedman #NonParametric #Stata
