Which Test?

Choosing a Statistical Test

A statistical test is a calculation that gives a p-value evaluating the evidence for a relationship or difference. Each test also produces a "test statistic" (e.g., Z, t, X², F,  r) which is usually not interpreted on it's own because each is on a different scale. The test statistic is converted to a p-value by a computer for interpretation.
