When you have more than two groups that you are comparing, you may need to use ANOVA. Dr Nic explains what Analysis of Variance does, with a special emphasis on how to interpret output and the hypothesis test involved. We include post hoc tests and the non-parametric Kruskal-Wallis test. Outputs from Excel and the open-source Jasp are used, with data about levels of qualification and household income. See for all of Dr Nic's videos organised by topic. Jasp statistical program can be found here: #DrNicStats #Statistics #Excel
