Question

Given the results of the preceding analysis, what can the researcher conclude? O Both the amount of time spent in the military and the different components of the program were related to severity of PTSD symptoms. However, the effect of each factor was independent of the other. O Veterans who took different components of the program had different PTSD symptom scores. By itself the symptom severity was unrelated to the number of years in the service; however, the different components of the program resulted in different levels of PTSD symptoms depending on the number of years in the service. 0 Neither the amount of time spent in the military nor the different components of the program was related to the severity of PTSD symptoms when looked at alone. However, there was an interaction between factor A and factor B such that PTSD symptom severity differed by component of the program depending on how long the veteran had been in the service. O Veterans who took different components of the program had different PTSD symptom scores. The PTSD symptom severity was unrelated to the number of years in the service either by itself or in conjunction with the differing components of the program

Explanation / Answer

1. df of Factor A is 0.0833 / 0.08 = 1
df of factor B is 12.1667/6.08 = 2
df of Interaction is 23.1667/11.58 = 2
df of Within is 56.50/1.35 = 42

2. F-ratio of Factor A = 0.06 < F critical value (4.07).
Therefore, there is no signifiance difference among the Factor A

3. F-ratio of Factor B = 4.50 > F critical value (3.22).
Therefore, there is signifiance difference among the Factor B

4. F-ratio of interaction of Factor A and B = 8.58 > F critical value (3.22).
Therefore, there is signifiance difference among the interaction of Factor A and B
