Permutation test

Permutation test is a type of hypothesis test. It tests the null hypothesis of no difference between 2 group distributions.
The data samples are sorted into 2 groups using permutations. The test statistic is calculated for each permutation to determine the result of the null hypothesis.
The test can be seen as resampling data.

It is used in studies, when we are interested, if the data of the 2 given groups comes from the same distribution or not. More than 2 groups can be compared (2 was used for illustration).
