Interpreting the results of two-factor ANOVA AaAa It is projected that approximately 580,000 veterans will take advantage of the GI Bill for the 21st century. Boots to Books is a course for all veterans, current military members, and their fanily members, friends, and supporters. The goal of Boots to Books is to assist deployed, post-deployed, and veteran students in making a positive transition from miltary to civilian Iife or from deployment to post-deployment life, including the acquisition of colege survival skills Posttraumatic stress disorder (PTSD) is quite common among combat veterans. Suppose that a researcher wants to revise the Boots to Books course in order to reduce the effects of PTSD. She recruits a group of combat veterans and collects data on the length of time they were in the milltary (factor A) and the potential components of the revised course (Community Service,Physical Activity, Journaling, and Meditation: factor B). She then assigns them one of the four components. The study will evaluate which components of the program are the most effective for reducing PTSD symptoms. The results of the hypothetical study are summarized by the corresponding sample means below. Each cell reports the average (M), the total (T), and the sum of squares (SS) of the symptom score (X) on the Clinician-Administered PTSD Scale (CAPS) of 10 veterans. Veterans are grouped according to the number of years they served in the military Factor B: Program Component Community Physical Journaling Meditation Sample Activity M 48.5 Service Totals Factor A: Years in Military M=51.5 T 515 SS = 172.5 M = 49 1-2 SS-102.5 M = 49 T = 490 ss = 60 M 49 T-490 SS-110.0 M = 49 T=490 M=55 T=550 SS-160.0 M 48 T=480 3-4 TA2 1,950 490 , M=47.5 T 475 SS 22.5 2-4 TA3 " 1,985 T 510 ss = 240 T = 500 Ss 110 aceExplanation / Answer
df = SS/MS
df A = 2
df B = 3
df interaction = 6
df within = 108
A - not significant as 3.84 < 4.81
B - not significant
interaction - significant as 3.757 > 2.97
