The weighted mean is used a lot by teachers. It is also called weighted average.You will learn how to calculate the weighted average using a real life example
Since the final exam usually carries more weight, this encourages students to work hard to improve their grade on the final exam
Even if students got some bad grades in the beginning, they may still pass the class with a good grade if they ace the final exam.
This happened to me a lot and teachers love to see and reward growth
Here is how a teacher may decide to grade his class. 10% for homework assignments, 15% for quizzes, 25% for a midterm, and 50% for the final exam
Notice that 10% + 15% + 25% + 50% = 100%
Suppose the maximum score is 100 and a student gets the following scores throughtout the year:
Homework assignments: 40, 50, 60, 50, 40, 30
Quizzes: 50, 60, 20, 50, 40, 80, 30, 70
Midterm: 65
Final exam: 95
