Bonjour, je doute sur un item:

"L’erreur de première espèce augmente quand la variance entre les populations diminue"

Item noté vrai.

Hors j'ai noté dans mon cours que alpha/beta diminuent quand la variance et erreur de mesure diminuent. D'où vient l'erreur?

Merci!

Salut,

Regarde en pj tu comprendra mieux :

Si α augmente quand (1- β) augmente, et que (1- β) augmente quand σ² diminue

alors :

α augmente quand σ² diminue

Du coups ton item est bien vrai. j'espère avoir répondu à ta question ❤️
