How does the bell curve relate to standardized tests like the SAT?

The bell curve, also known as the normal distribution, is a statistical concept that helps to illustrate how scores on standardized tests like the SAT are distributed among the test-takers. In a bell curve distribution, most of the scores cluster around the average, with fewer scores appearing as you move away from the average in either direction.

This means that a large number of students score around the mean, while fewer students achieve very high or very low scores. This distribution allows educators and institutions to understand not just individual performance, but also how students' scores compare to those of their peers. Many standardized tests, including the SAT, are designed to reflect this normal distribution, which aids in interpreting results and making decisions based on them, such as college admissions.

In contrast, the other answer choices do not accurately capture the relationship that the bell curve has with the SAT scores. Adjustments for grading, predictions based on GPA, and emotional responses do not pertain to the statistical distribution of test scores in the same way that the concept of a bell curve does.
