A friend of yours, a senior, took the Graduate Record Exam in September and scored in the 99th percentile. In February your friend took the same exam over again. This time your friend scored in the 84th percentile. As a research methodology student, you told your friend that his/her lowered score was probably due to:

a) testing
b) history
c) statistical regression
d) demoralization

d) demoralization

Step-by-step explanation:

I will tell him that it happened due to the demoralization. The first time you got 99th percentile and the second time for the same exam you got 84th percentile, it denotes that you had been demoralized and it may happen due to thinking too much about your reputation among friends that what will happen if you would not get the same or higher percentile on the second time test.
