You had two groups of researchers getting data on a new drug for Alzheimer's patients with working memory loss. Both of the researchers give the same memory task performed using the Wisconsin Card Sorting Task and count the number of correct answers from 15 patients each. The results of Researcher A are: 60, 62, 70, 55, 78, 53, 78, 53, 70, 66, 62, 79, 51, 65, 69 The results of Researcher B are: 68, 75, 71, 65, 58, 74, 68, 72, 60, 59, 72, 65, 70, 72, 69 Which set of scores had a lower SEM? You should be able to do this just by looking at the raw scores, but of course you can do the math if it helps you answer the question.
