Question

Post tests such as Scheffe are not necessary for an analysis of variance comparing only two treatment conditions. True False A research study comparing three treatments with n = 5 in each treatment produces T_1 = 5, T_2 = 10, T_3 = 15, with SS_1 = 6, SS_2 = 9, SS_3 = 9, and sigma X^2 = 94. For this study, what is SS_total? 10 24 34 68 After an ANOVA a researcher computes eta^2 to evaluate effect size and obtains eta^2 = 0.50. If the ANOVA had SS_total = 100, then SS_within = SS_between = 50. True False

Explanation / Answer

True, because, post test such as scheffe are necessary for an analysis of varaince comparing two or more

treatment condiiton.
