POST Hut NOw that You rejected the null hypothesis; you need treatments are more effective; runan Matmeni _ Maybe one analya Lnealanen deletirune maybe tWO treatments are equally effective but both are beuol bcttet Itun which than Ihc allthe 4hjsis will determine which of these possibilities occurred thutd uer05 could - WCWM While Therc Hlollx up follow-up [ests WC only cam ont this text many the KSD; duleter @fetence follow-up test This test produces mean difference that you honestly = significantly different from each other significant ol mcans. Any differences daictmine the difterence larger than the HSD valuc: belxicen two means palrs snficant If 4 Ito Ican? an (or more) , the difference aflercnt by = 4notnt unlikely [0 have resulted from chance = probably created by the treatment differences You compute the HSD as Rhitntet can lock upq Appendix by' using the number TreJUNEn conditions (g) the dfierer' and_ alpha Iihue Your the number of participants each condition. The MS_ comes from the Fratio calculation you did earlier Compute the HSD for this analysis now: Aaameemt KSD = Cczipute the differences berween each pair of treatment conditions The first one cone for you: 4-book vs. 20-book: 30 40-book = book: #book book: Based 0n the HSD you computed Question 33 and the condition mean differences You (cmputed for Question 34. which of the three group mean differences are so large that they are Etlcly have been caused by chance? Choose all that apply: The difference between the 40-book group and the book group diference = between the 40-book group and the 20-book group diflerence between the 20-book group and the book group Na that yoU " Qton - identified which group differences are larger than the HSD you computed in 4105 Siaie, which ones are unlikely to result from sampling error), you need to compute Fnthe { each pairwise comparison (. those you computed in Question 35). This done following ! Kdcompated : formula which the numerator the difference berween the Ewo conditions UAaons and the denominator is the square root of the pooled variance for those two M-M SD;
