Quizplus · Accepted Answer

The best procedure for selecting who will be in the group given a car is to randomly select participants and then assign them to either the car group or the public transit pass group. This can be done by flipping a coin, which is a fair and unbiased way to make the decision. This will help to ensure that the groups are similar in terms of their demographics and other characteristics, which is important for the validity of the research. Selecting by age, residential area, or education level may introduce bias and affect the results of the study.
