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.
Or, this can be accomplished by weighting the class means by the number of students in each class (using a weighted mean of the class means): Â¯ = (Ã) + (Ã) + = Thus, the weighted mean makes it possible to find the average student grade in the case where only the class means and the number of students in each class are available. Convex combination example Since only the relative weights are relevant, any weighted mean can be expressed using coefficients that sum to one.
