Quiz 6 Psyc 541 Summer 2022 Online 1. (15 points) In a study of postmeningitic and postencephalitic brain damage, each subject was given a battery of tests, providing a composite score for each. Low scores for the composite measure presumably represented a considerable degree of residual brain damage. The subjects were divided into three groups according to type of initial infection and into three crossed groups according to time since apparent physical recovery from the illness. The data are below. Fill in the correct omega squared and cohen F for each source of variance. Postencephalitic Postmeningitic Postoperative Control Type of Infection Time Type x Time Error 1-2 Years 71.7 82.0 71.75 Conclusions: Tukey: Conclusions: LSD; SS 2413.556 536.222 2 2194.444 4 2290.75 27 7-10 years Conclusions: Tukey: Conclusions: LSD: 25 points df 2 3-5 Years 62.25 79.25 81.75 MS 1206.778 268.111 548.611 84.843 7-10 Years 50.00 60.0 89.75 F 14.224* 3.16 6.466* *p<.05 What is the average variance within the groups? (put in a number) What is the variability of the Type of Infection Means ignoring the effects of time? (puti a number) omega sq Cohen F How many subjects are in each group? What is the variance of the cell means around the grand mean after the variability due to the main effects has been removed. If the variability among the main effect means of Time was no greater than you would expect by chance, what should the F value be for testing the main effect of time. Complete subsequent Tukey Tests and LSD tests on all significant effects and state your conclusions. When conducting post hoc tests for the type of infection x Time interaction, I want you to examine the effects of type of brain damage at each level of time.
