High School

The SAT Mathematics scores of seniors in a large school district in the Northeast have a mean of 512 and a standard deviation of 84.

Interpret the value of the mean:

A. If a person takes the SAT Mathematics test once, their score will be around 512.
B. The mean does not have a meaning in this context.
C. When a group of students takes the SAT Mathematics test, the group's average score will be about 512.
D. Everyone who takes the SAT Mathematics test will score about 512.

Answer :

The mean of 512 represents the average SAT Mathematics score among seniors in a large school district in the Northeast. It provides information about the typical score achieved by the group as a whole, rather than predicting the score of any individual student.

The value of the mean, which is 512 in this case, represents the average SAT Mathematics score of seniors in a large school district in the Northeast. It is the central measure of the distribution, indicating the typical or average score among the group of students. When interpreting the mean, it is important to note that it provides information about the group as a whole, rather than individuals. The mean of 512 suggests that, on average, the students in the district obtained a score around that value. However, it does not imply that every individual student will score exactly 512.
