Final answer:
The equation associated with one-way within-subjects analysis of variance is the F ratio.
Step-by-step explanation:
The equation associated with one-way within-subjects analysis of variance is the F ratio.
The F ratio is calculated by taking the variance between samples, which is an estimate of the population variance, divided by the variance within samples, which is an estimate of the error variance.
The F ratio follows an F distribution with (number of groups - 1) as the numerator degrees of freedom and (number of observations - number of groups) as the denominator degrees of freedom.
