A repeated measures ANOVA is statistically more powerful than a randomized ANOVA. One reason is that the same subjects are used (like a paired t test). Why else? The within source of variance in a randomized ANOVA becomes ___subject______ and __error________in a repeated measures ANOVA. Only the __error_____ is used to calculate the F ratio. Because the denominator is smaller, the F ratio will be ___?____ and more likely to ______?_________ . Hints: error, fail to reject the null hypothesis,...
