More about: Partial Eta²

What it calculates

The “Partial Eta²” calculator computes Partial η² from 2 parameters: ss_effect, ss_error.

A core calculation for studying, engineering tasks, and checking solutions.

Example calculation

With parameters SS_effect = 100, SS_error = 400 the result is 0.2 (η²_p = SS_eff / (SS_eff + SS_err)).
