Quizplus · Accepted Answer

The best choice would be to obtain a representative sample of elderly people. This would ensure that the sample accurately reflects the characteristics of the larger population of elderly people, and would provide the most generalizable findings. Selecting only elderly acquaintances or athletic individuals may introduce biases into the sample, while selecting individuals not known to the psychologist may not guarantee a representative sample.
