A researcher aims at evaluating the effectiveness of magnetic therapy for treating chronic elbow pain. The researcher randomly selected 20 patients for the study and divided them into two groups:
Group 1 (n=10): patients are given magnetic therapy (treatment group)
Group 2 (n=10): patients are given usual care (control group)
After having the treatment for one month, the patients completed a questionnaire to evaluate their pain level. The data of this study are as follows:
Group 1 (treatment group): 10, 10, 12, 12, 14, 14, 15, 16, 17, 17
Group 2 (control group): 13, 13, 15, 15, 18, 18, 19, 19, 20, 20
Based on the above data, you want to know if it is reasonable to conclude that magnetic therapy has an effect on patients’ chronic elbow pain.
(a) What is the appropriate t-test for the analysis of the above question?
(b) What are the null hypothesis and research hypothesis for the study?
(c) Using SPSS to conduct the appropriate t-test and report the results in APA format. Please also print out and submit the SPSS output.
