Statistical test selection

The type of hypothesis test to use depends on the nature of the investigation and the type of data available.

Statistical tests that compare the means (medians) for one, two, three or more groups/samples


And for proportions..





parametric statistical test is one that makes assumptions about the parameters (defining properties) of the population distribution(s) from which one’s data are drawn, while a non-parametric test is one that makes no such assumptions
