    ANOVA vs Kruskal-Wallis for combined normal and non-normal data

    I have a number of distributions that I need to determine significant differences. However, some distributions are normal and some are not. In order to properly compare the p values/significance between these distributions, should I use only the Kruskal-Wallis test on all distributions or just...

    Which test to use for these variables and their associations

    Hey, I have some questions about which test I can or have to use. Which test do I use to only identify if there is a relationship between those variables? I only want that to know, for the identification of confounding factors. Ordinal dependent categorical variable <-> ordinal...

    p-value associated with Kruskal Wallis with multiple comparison?

    I have a data set that shows the differences between 3 different controllers of a biomechanical system on the same performance metric (specifically, I measure each controller's performance on a set of N tasks, and record the percentage of tasks that achieve success (i.e. the controlled segment...

    Is repeated measures ANOVA appropriate for my data set?

    My project involves designing various controllers of a biomechanical system, and then once the controller design is complete, testing each controller on a single, standard set of 500 tasks, and determining the performance of each controller on this single set of tasks, so that I can compare the...
