A Clinical Psychologist wants to know what color is the most relaxing, to design new “calm” waiting rooms for dentists. Three different colors are viewed by participants and rated on a scale (0 – 10) to quantify the level of relaxation caused by the color. The n value and mean for each color are shown below, higher scores mean greater relaxation. Complete the source table below and answer the accompanying questions. Red Green Blue n = 9 n = 9 n = 9 M = 1.9 M = 3.2 M = 4.3 Source SS df MS Fcalculated Fcritical p level Between Treatments ___28__ ____ _____ ______ _____ p __ .05 Within Treatments __110_ ____ _____ Total _______ _____ What was the dependent variable ( D.V. ) in this study? __________________ What was the independent variable (I.V.) in this study? ___________________ Was there a significant effect? ______________________________________ Write an APA formatted summary of this study below.

df Between Treatments = Number of groups - 1 = 3 - 1 = 2
df Within Treatments = Number of observations - Number of groups = 9 * 3 - 3 = 24
MS Between Treatments = SS Between Treatments / df Between Treatments = 28 / 2 = 14
MS Within Treatments = SS Within Treatments / df Within Treatments = 110 / 24 = 4.58
Fcalculated = MS Between Treatments / MS Within Treatments = 14 / 4.58 = 3.057
Fcritical for df = 2, 24 and 0.05 significance level is 3.40
