Question

Quizplus · Accepted Answer

Comparing the achievement of students who won the lottery with the achievement of students who lost the lottery is the best approach because it allows for a direct comparison between students who had the same chance of attending a private school but ended up in different groups. This minimizes the effects of selection bias and allows for a more accurate assessment of the impact of vouchers on student achievement. Comparing with the average student in the public school (A) or with students in public schools (B) would not allow for a direct comparison between students with similar characteristics, while comparing with schools with increased enrollment or decreased enrollment (D) could be influenced by other factors such as school resources or teacher quality.
