Document Summary
Sstotal = ssb(rows) + ssb(columns) + sswithin + ssinteraction. F = msb(columns) main effect of variable b (columns) Correction from week 9 slides: formula for tukey"s hsd test. What formula(s) does this 1 remind you of ? sm. Where: sm = mswithin basically the same as in previous formulas, except we use. N variance (msw) as numerator instead of sd, & divide by n instead of n b/c we the whole thing. 2-way (factorial anova) effect size & post hoc tests. Correlation: measurement of correlation: pearson product-moment correlation, interpretation of correlation coefficient, factors that affect correlation coefficient. 2-way independent groups anova: nh myth busting : step 4. A significant interaction between age and repetitions was obtained, f(1,8) = 8. 26, mse. Additional repetitions reduced errors for younger participants but increased errors for older participants. Effect size calculations for 2-way independent groups anova need to be done for each main effect & interaction.
