What would the IV and DV be in this case, how would you select the 20 patients and would you use a one tailed or two tailed test?
You are interested in examining the effect of psychological therapy on chronic pain patients' level of pain reduction. You want to select a sample of 20 chronic pain patients from a pain clinic comprising of 100 patients. You decide to test pain levels at baseline and again following four weeks of psychological therapy. You decide to compare them with another similar group of chronic pain patients who did not receive psychological therapy during that period of time. You anticipate that pain levels will decrease significantly following psychological therapy.
Thanks
