Le calcul de taille d’échantillon exige des hypothèses chiffrées : taux de conversion actuel (ou métrique de base) et effet minimal détectable (MDE) à 5 % de significativité et 80 % de puissance. Précisez-les dans le prompt, sinon la réponse restera générique. Ajoutez aussi le seuil d’arrêt : probabilité de dégradation d’une guardrail à ne pas dépasser pour décider en cours de test.
