La Formule

Moyenne = Σ(valeur × poids) ÷ Σ(poids). Maths (14, coeff 4) + Français (12, coeff 3) = (56+36)÷7 = 13,14. La moyenne pondérée est utilisée partout : notes scolaires, indices boursiers, évaluations.

vs Simple

Moyenne simple : (14+12)÷2 = 13. Pondérée : 13,14. La différence existe quand les poids ne sont pas égaux.
