Situation 1
The Rehab Center has 40 separate family counseling groups, each with about 30 participants. The director of the Center has noticed a decline in attendance rates and has decided to try out an experimental program to improve them. The program is very expensive, and the Center can only afford to finance a 250-person program at first. If the evaluator randomly selects individuals from among all group members, this will create friction and disturb the integrity of some of the groups. As an alternative, the evaluator has suggested a plan in which five of the groups—150 people—will be randomly selected to take part in the experimental program and five groups will participate in the control.
Situation 2
The Medical Center has developed a new program to teach patients about cardiovascular fitness. An evaluation is being conducted to determine how effective the program is with males and females of different ages. The evaluation design is experimental, with concurrent controls. In this design, the new and traditional cardiovascular programs are compared. About 310 people signed up for the winter seminar. Of these, 140 are between 45 and 60 years old, and 62 of these 140 are men. The remaining 170 are between 61 and 75 years old, and 80 of these are men. The evaluators randomly selected 40 persons from each of the four subgroups and randomly assigned every other person to the new program and the remainder to the old program.
Situation 3
A total of 200 health education teachers signed up for a continuing education program. Only 50 teachers from this group, however, are to participate in an evaluation of the program’s impact. The evaluator assigns each participant a number from 001 to 200 and, using a table, selects 50 names by moving down columns of three-digit random numbers and taking the first 50 numbers within the range 001 to 200.
