Before we approach the subject of how to calculate weightedaverages, let’s understand the basic averaging formula. When you have several values (a1,a2,…, an), the average (or mean) value can be calculated as follows: AVG = Σ(a1+a2+…+an) / n ...
Weighted mean = Σwx/Σw Σ =summation(in other words…add them up!). w = the weights. x = the value. To use the formula: Multiply the numbers in your data set by the weights. Add the numbers in Step 1 up. Set this number aside for a moment. ...

While countries and institutions use a range of alpha-numerical grading scales, their formulas for calculating a student's cumulative grade point average (CGPA) score are basically the same. In mathematical terms, the CGPA score is a "weighted mean," wherein the influence each grade has on ...
Arithmetic-Geometric Mean This is used mostly in calculus and in machine computation (i.e. as the basis for many computer calculations). It’s related to the perimeter of an ellipse and when it was first developed byGauss, it was used to calculate planetary orbits. The arithmetic-geometric ...
