Concept explainers
To identify: Average for each class would a teacher use to compare the academic work of two classes out of the three options.

Answer to Problem 15CT
A. The average of students’ quiz grades
Explanation of Solution
Explanation: Option A. It is the right option as a teacher wants to compare the academic work of two classes, and academic work can be compared with the help of average of students’ quiz grades.
Option B. It is a wrong option as final grades of a student can include academic as well as other grades such as co-curricular activities, attendance etc. Therefore, final grades cannot be the right option to compare the academic work.
Option C. This option is incorrect because average number of students’ absences cannot help in comparing the academic work.
