Question

Quizplus · Accepted Answer

The fact that age and cohort are confounding variables means that it is not possible to determine whether increased vacations in January are due to age or the historical time in which one lived. The study does not provide any evidence that increased age caused participants to vacation more, and the sex of the participants is not mentioned as a variable in the study. The time of measurement is not a confounding variable in this case, as the study is focused on the vacation habits of 70-year-olds regardless of when the study was conducted.
