Question

A friend of yours, a senior, took the Graduate Record Exam in September and scored in the 99th percentile. InFebruary, your friend took the same exam over again. This time your friend scored in the 90th percentile. As aresearch methods student, you told your friend that his/her lowered score was most likely due to: differential selection. compensation rivalry. testing. demoralization. statistical regression

Answer 1

Answer:

"differential selection"

Step-by-step explanation:

If your friend took the test twice and passed both times with a score above 90% then the minor difference in price is most likely due to "differential selection". The first test had  questions that he had a little more experience in solving, while the second time he was most likely given a couple questions that he wasn't as prepared for as he was the first time. This is most likely the cause for the difference in percentiles.
