If you have to perform the comparison between multiple groups, but you can not run a ANOVA for multiple comparisons because the groups do not follow a normal distribution, you can use the Kruskal-Wallis test, which can be applied when you can not make ...

Analysis of variance: ANOVA, for multiple comparisons
The ANOVA model can be used to compare the mean of several groups with each other, using a parametric method (assuming that the groups follow a Gaussian distribution).
Proceed with the following example:
The manager of a supermarket chain wants to see if the consumption in kilowatts of 4 stores between them are equal. He...

Non-parametric statistical hypothesis test, for the comparison of the means between 2 paired samples
The mayor of a city wants to see if pollution levels are reduced by closing the streets to the car traffic. This is measured by the rate of pollution every 60 minutes (8am 22pm: total of 15 measurements) in a day when traffic is open, and...
