Pour chaque test, veillez à ce que la taille d'échantillon minimale soit calculée avec un outil de significativité statistique (ex. sample size calculator d'Optimizely). Un piège courant : tester trop de variables simultanément sur une petite liste biaise les résultats. Commencez par la variable à plus fort levier prévu.
