2 way independent groups anova: mythbusting anova summary table. Total: the only thing as a researcher that you are interested in are the f variables. 11: telling us that we have a significant age effect and significant axr effect, but not a significant repetition effect. Step 2: 3 f critical required: one for each independent variable and noe for the interaction, assu(cid:373)e = (cid:1004). (cid:1004)5, degrees of freedom, df-age = 1, df-rep = 1, df-int = 1, df-within = 8. F values: f-age = 5. 32, f-rep = 5. 32, f-int = 5. 32. F-values taken from the anova summary table: f-age = 13. 08, f-rep = 0. 00, f-int = 8. 26. Step 4: obtained f-age (13. 08) > critical f-age (5. 32), obtained f-rep (0. 00) < critical f-rep (5. 32), obtained f-int (8. 26) > critical f-int (5. 32), older participants made significantly more errors (m=0. 26) than younger participants (m=0. 16),
