Your friend, Jason, took the Graduate Record Exam in September and scored in the 98th percentile. In April, Jason took the same exam again. This time your friend scored in the 87th percentile. As a research methods student, you told your friend that his lowered score was most likely due to:

Statistical regression.

Explanation:

Statistical Regression can be defined as a technique that is used to examine that how an independent variable affects a dependent variable. In simple terms, this method helps to determine how an independent variable will bring changes in a dependent variable.

In the given case, the dependent variable is the percentage scored by Jason, whereas an independent variable will be change in period. The first time Jason took the test was in the month of September and the second exam was given in April. Because of the time gap between the two exams, there's a tendency to forget many of the things which may lower the score, from the first one.

So, the correct answer is statistical regression.

    racial conflict and discrimination has existed ever since man learned to kill with rocks and bones. these conflicts arose from disputes between territory, power, wealth, religion, or simple difference. some of the most infamous racial disputes include slavery, the holocaust, and the civil rights movement.

    these listed disputes often resulted in casualties from all sides. riots, wars, imprisonment, and lynching are all commonly associated with racial conflict on severe levels.

      however, racism is an improving issue in recent decades. people are being more accepting and welcoming of diverse populations. though, the world isn't perfect and it will take much more time, if ever, until the world is rid of racism.
