Marc, a high school senior, was given an eighth-grade science exam and he scored 85%. Is this an accurate predictor of how well students in the eighth-grade science class will perform on the exam?
No, because Marc is not representative of the population in the eighth-grade class No, because Marc scored too high on the test Yes, because Marc scored high so the test is easy Yes, because Marc is representative of the population in the eighth-grade class
Marc is a high-school senior. Does his score on the science exam reflect eighth-graders' potential scores? No, because Marc is not an eighth-grader. In fancier terms, No, because Marc is not representative of the population in the eighth-grade class.
