Question 1

A procedure in which two groups are compared based on whether they were part of an initially specified random sample subjected to an experimental protocol is called

◦ intention to treat.
◦ regression discontinuity.
◦ difference-in-differences.
◦ causality.

Question 2

Refer to the information provided in Scenario 36.3 below to answer the question(s) that follow.

SCENARIO 36.3: Consider a local high school that has 300 sophomores considered to be at-risk students. A privately-sponsored after-school sports program has been established to try to help at-risk students succeed in finishing high school. The local government wants to know if this program reduces the students' probability of dropping out of high school before the end of their junior year, and decides to randomly sample 150 of the 300 at-risk sophomores and invite them to attend the after-school program at no cost. 100 students accept the invitation, and by the end of their junior year, the drop-out percentage of the 100 students who attended the program was lower than the drop-out percentage of the 200 students who did not attend the program. 





Refer to Scenario 36.3. Based on the information in the scenario, can you conclude that the after-school program had a positive effect?

◦ Yes, because the drop-out percentage for those students who attended the program was lower than the drop-out percentage for those students who did not attend the program.
◦ No, because less than half of the at-risk students attended the program.
◦ Yes, because the 150 students offered the program were a random sample.
◦ No, because we cannot assume the 100 students who accepted the offer were a random sample.

Refer to Scenario 36.3. Based on the information in the scenario, the 100 students who accepted the offer to attend the after-school program is an example of

◦ selection bias.
◦ a random sample.
◦ survivor bias.
◦ positive correlation.

Refer to Scenario 36.3. The efficacy of this program can be best measured by comparing

◦ the drop-out percentage of the 100 students who attended the program to the drop-out percentage of the 200 students who did not attend the program.
◦ the drop-out percentage of the 100 students who attended the program to the drop-out percentage of the 50 students who were offered the program but chose not to attend.
◦ the drop-out percentage of the 150 students who were offered the program to the drop-out percentage of the 150 students who were not offered the program.
◦ the drop-out percentage of the 50 students were offered the program but chose not to attend to the drop-out percentage of the 150 students who were not offered the program.

the drop-out percentage of the 150 students who were offered the program to the drop-out percentage of the 150 students who were not offered the program.
