Document Summary
Independent samples (between subjects), dependent samples (within subjects). Anova statistic is f. k= # of levels. X = t, t = g, n= total # of subjects, ns = no significant difference, sig = significant difference, n= # of subjects for each level. Between subjects anova: notations: -iv"s are called factors; each condition of factor is called level, -one-way anova uses conditions from 1 iv. : -researchers more often have more than two levels to study, -more accurately describes the relationship (linear, nonlinear), -maximum information for cost and effort. : -experiment-wise error rate would be alpha=0. 15 if three separate. Anova"s keep the experiment-wise error at the alpha you selected by simultaneously different alphas. Assumptions: -dv measured on interval/ratio scale, -scores are normally distributed, -independence observa- tions, -homogeneity of variance (will not be testing). Post hoc: (tukey"s hsd test): -done when you reject the null hypothesis and k>3 (difference is significant),
