A statistician studies the relationship between income and the choice of individuals to attend college. He notices that during a
particular time period, the average individual income doubled but fewer individuals attended college. He concludes that income is negatively related to college enrollments. The statistician has failed to account for the fact that tuition rates tripled over the same time period. Why is the reported conclusion misleading in this case?
The conclusion is is misleading because the extraneous variable, cost of tuition was not accounted for in the experiment.
