η^2 value (SS Effect/SS Total)
Partial η^2 value (SS Effect/SS Residual)
η^2 overestimates the variance explained in the population (i.e., it is a biased estimator), but as the sample size gets larger the amount of bias gets smaller. Grissom and Kim (2012, p. 182–183) suggest alternative estimators.
