Identifying individuals with a high risk of Alzheimer’s disease usually involves a long series of cognitive tests. However, researchers have developed a 7 Minute Screen which is a quick and easy way to accomplish the same goal. The question is whether the 7 Minute Screen is as effective as the complete series of tests. To address this question Ijuin et al. administered both tests to a group of patients and compared the results. The following data represent similar results to those obtained in the study. Patient 7-Minute Screen (x) Cognitive Series (y) A 3 11 B 8 19 C 10 22 D 8 20 E 4 14 F 7 13 G 4 9 H 5 20 I 14 25 Compute the correlation to measure the degree of relationship between the two test scores? What percentage of variance for the cognitive scores is predicted from the 7-Minute screen scores?
