Question

If you know a student's average grade can you tell what the student's individual test scores were? Why or why not?

Answer 1

No because you can get the same average with different numbers. You'd need more information regarding his tests.

Answer 2

For example take the average of n+x=10; 10/2=5. So an avg of 5 for that. So if n and x are tests, we can have 1+9, 2+8,3+7, 4+6, 5+5..etc so we really don't know what his actual test scores were.

Answer 3

Thank you!!
