Researchers studied a group of 30 “self-designated worriers” (i.e. individuals who reported spending at least 10% of the day worrying) and who were over the age of 70 (mean age of 78.1). The researcher randomly assigned the worriers into three groups. For the next four weeks, each group would experience a different approach to handling worry. One group engaged in a worry-focus discussion group. The second group members enjoyed individual therapy. The third group went for daily walks in the park. Data was collected, analyzed, and interpreted. 41. The above design utilizes what type of group assignment technique: a. mixed factorial with combined assignment (mixed combo). b. repeated measures. c. nonequivalent groups. d. independent groups. e. quota sampling
