Chapter 5: Producing Data Example 3: An educational psychologist wants to test two different memorization methods to compare their effectiveness to increase memorization skills. There are 120 subjects available ranging in age from 18 to 71. The psychologist is concerned that differences in memorization capacity due to age will mask (confound) the differences in the two methods. What would the design look like? Example 4: Men and women experience different physiological differences among diseases. In a study of blood pressure three different methods (a drug, yoga, and meditation) will be tried on both men and women randomly selected from a large company to see which is most effective in reducing high blood pressure. Construct an appropriate design diagram. Would a control group be necessary? Explain. Can this experiment be blinded? What is the parameter of interest in this experiment? What is the population of interest in this problem? Homework: Day 2: pg 371-377 problems 5.45, 48, 50, 52, 54, 56-58
