A study estimated the percentage decrease in pain ratings

A study estimated the percentage decrease in pain ratings following 60 minutes of guided relaxation. The result was 34% [19, 49].

a. What is the point estimate of the decrease? The interval estimate? The 95% CI? MoE?

b. Make two statements about what the CI tells us. Give your interpretation of the results.

c. Considering Open Science, what concerns do you have?

2) Suppose the result from the pain study had instead been 13% [−3, 29]. Answer all the same questions.

3) You are considering a replication of the pain study of Exercise 1 above.

a. Supposing you want MoE from the replication to be about half of MoE from the original study, describe your replication study.

b. Invent the results of such replication. Compare with the original results.

c. Suppose you meta-analyze those two sets of results. Suggest roughly what results the meta-analysis might give, and interpret those.

d. What’s the value of replication and meta-analysis?
