a. use a computer program to select the locations have a rewards program and those that don't.
Step-by-step explanation:
Randomization refers to an important statistical procedure used to eliminate bias in a study. With randomization, all subjects in the study possess equal chances of being selected. In the study scenario described above, randomly choosing half of their total location to partake in the reward program would involve the use of a technique which isn't liable of introducing bias into the study either deliberately or systematically. The use of store managers or other human in the selection process won't be totally convincing at preventing bias. Hence, a computer program will do.
