How it works
The arithmetic mean is the sum divided by the count. A weighted average multiplies each value by its weight, adds them up and divides by the sum of weights — this is how grades with coefficients work. The geometric mean suits growth rates and ratios; the harmonic mean suits averages of speeds or prices per unit.
