Distribution normale N(0, 1): centiles (et déciles) de la fonction de répartition
Lecture de la table
X désignant une variable aléatoire normale d'espérance 0 et d'écart-type 1, c'est-à-dire une variable aléatoire normale centrée réduite, on peut lire dans la table ci-dessous, par exemple, que
P(X ≤ -1.28155) = 10 %
P(X ≤ 1.28155) = 90 %
Interprétation
Au moyen de la règle
P(a < X ≤ b) = P(X ≤ b) - P(X ≤ a)
on peut déduire, par exemple, que
P(-1.28155 < X ≤ 1.28155) = (90 %) - (10 %) = 80 %
