Simulated Research Study #4People who live in underserved remote areas do not have adequate access to professional counseling services for alcohol abuse. Improvements in internet access and video conferencing technology may provide a means of delivering counseling services to underserved remote areas. Thepurpose of this study is to investigate the efficacy of a technology based delivery system for counseling services. The researchers designed a study with a sample of N = 40 participants who livein an underserved remote area and who have entered counseling for alcohol abuse. The participants will be randomly assigned to one of two groups, face-to-face counseling or video conference counseling. Both groups will use the same counseling model and will have the same number of sessions over a three month period. The difference between the groups will be how counseling services are delivered. Participants will complete the Alcohol Dependence Scale (ADS) at the end of treatment. The groups are considered equivalent at the beginning of the study based on random assignment to groups. The null hypothesis states there will be no difference in scores on the ADS between face-to-face counseling and video conference counseling. The researcher uses a between groups t-test to compare the post treatment scores of the ADS for the two groups. The scores on the ADS for the two treatment groups are:Face-to-Face CounselingVideo Conference Counseling58141210951110756131297

I believe for this research type the study design that was used was was a independent-groups t-test. Because the study includes two compared group (participants who were involved in face-to-face counseling and participants who did video conference). Also the study involves comparing the means of two different samples of participants.Does the study design accurately test the null hypothesis? The study design did accurately test the null hypothesis.Is the correct statistical test used to analyze the data? Why? Why not?Yes, the correct statiscial test was used to analyze the data because the test gives way to determine whetherthe null hypothesis would be rejected or accpeted in this study.
COUC 515Regardless of whether or not the correct statistical test was used, are the results statistically significant? Social science research uses a p value of .05 to determine statistical significance. Because the probability value (p-value) is p= 0.798, which is a higher than the 0.05 level of significance which proves that the results do not prove statistically significants.Does the researcher reject or fail to reject the null hypothesis? The researcher does fail to reject the null hypothesis.What are the implications of the results for the study and the counseling field? The conclusion that can be drawn from the result is there is no distinction between scores between groups (face-to face counseling and video counseling).
