weighted rating $(WR) = (v / (v+m)) R + (m / (v+m)) C$ where: $R$ = average for the movie (mean) = (Rating) $v$ = number of votes for the movie = (votes) $m$ = minimum votes required to be listed in the Top 50 (currently 1000) $C$ = the mean vote across the whole report (currently 6.8) Now, I was wondering how I would implement it for my situation.
The student has earned the following scores for each category: tests-83, final exam-75, quizzes-90, homework-100. We need to calculate the student's overall grade. To calculate a weighted average with percentages, each category value must first be multiplied by its percentage. Then all of these new values must be added together. In this example, we must multiply the student's average on all tests (83) by the % that the tests are worth towards the final grade (40%).
