In some schools, primarily public high schools, weighted-grade systems give students a numerical advantage for grades earned in higher-level courses or more challenging learning experiences, such as honors courses, Advanced Placement courses, or International Baccalaureate courses.
Example of a weighted average calculation: Assume you have taken five quizzes with the following scores out of 10 possible points. 10 pts, 5 pts, 10 pts, 10 pts, 10 pts. The average score will be 9 pts.average = (1/5)(10 pts + 5 pts + 10 pts + 10 pts + 10 pts) = 45 points total / 5 = 9 pts The low score doesn't shift the average down much because the four 10 point scores weight the average toward nine. Here the high scores occurred 4 out of 5 times or 80% of the time.ou can calculate the weighted average in the following way. Literally what happens in the calculation is average score = [40 points + 5 points][1/5] = [45 points] = 9 points. Assume you have taken five quizzes with the following scores out of 10 possible points. 10 pts, 5 pts, 10 pts, 10 pts, 10 pts.
