, Quiz: Methods, Program Evaluation, and Designs: FSPC515: Research and Program Evaluation (D02) 4/10/2G, 4:35 PM
before participating in the workshop and one week after participating in the workshop?
In order to measure relationship satisfaction, Kendyl researches a reliable instrument called “Enrich Marital
Satisfaction Scale” (Fowes & Olson, 1993) and gives this scale to couples before participating in the workshop
and then again one week after participating. When analyzing the data, what statistical test should Kendyl use to
answer the research question and why? (3 points for correct test listed and 4 points for rationale)
Your Answer:
Kendyl should use a paired samples t-test when investigating the eYcacy of counseling programs associated with
enhanced relationship satisfaction.
Using a paired samples t-test is the best option for Kendyl because it's what is used to analyze the mean difference
between two scores collected from the same group of participants at different points in time, since data was
collected both before and after week after the treatment at the workshop.
Question 2
Not yet graded / 7 pts
Kendyl decides to use a Paired Samples T-Test and her results indicate a pretest mean of 31.3667 (SD
= 6.31082) and a posttest mean of 34.9667 (SD = 6.65652), p = .000.
1. Did Kendyl use the correct statistical test?
2. Despite whether Kendyl used the correct test, what do these results indicate?
(3 points for correct answer, 4 points for results explanation).
Your Answer:
1. Yes, Kendyl used the correct statistical test based off of the fact that the couples were measured two times
(before and after treatment).
2. The null hypothesis is rejected because p is less than 0.05, p=.000, meaning there was a signi]cant increase in
the mean scores, further meaning that there was an increase in the satisfaction of couples.
