Null Hypothesis

A statement suggesting that there is no significant difference or effect, and any observed difference is due to chance.

Identical Populations

Populations in statistical studies that have exactly the same characteristics, distributions, and parameters.

Permutation Resamples

A statistical technique for obtaining null distributions by calculating all possible values of a test statistic under rearrangements of the observed data.
