Question
Chapter 1, Problem 1.72E
Interpretation Introduction
Interpretation:
The average grade using equation 1.32 if the scores on a 10-point quiz are 5, 5, 5, 5, 10, 10, and 10 is to be calculated.
Concept introduction:
Grade average is a measure of a student's achievement in academics at a college or university level and it is calculated by dividing the total number of points of grade obtained by the total number attempts made by a student. A student’s grade point average results in a mathematical mean or average of all final grades.
