Question 1

What is a normal distribution and why is it important in understanding student performance?

Accepted Answer

A normal distribution represents the way test scores would fall if a test was given to every single student of the same age or grade in the population.It is typically depicted by the bell curve.
It is important in understanding student performance because it can be used to show how students,as a group,performed on a measure indicating excellent,average,or poor performance.
