An industriаl psychоlоgist is investigаting the effects оf work environment on employee аttitudes. A group of 20 recently hired sales trainees were randomly assigned to one of 4 different "home rooms" with 5 trainees per room. Each room was identical except for the color of the walls. The 4 colors used were light green, light blue, gray, and red. Therefore, in this experiment the 4 treatments were the 4 room colors. The psychologist wants to compare the mean attitudes of the trainees assigned to the 4 rooms with different colors. At the end of the training program, the attitude of each trainee was measured on a 60 point scale (the lower the score, the poorer the attitude). The data were subjected to an analysis of variance. The partially completed Analysis of Variance (ANOVA) table was as follows: Source df SS MS F Total 1,829.75 Treatments 1,678.15 Error 151.60 Find the Mean Squares for treatments.
