Hello , je force un peu sur l'espace biostat du forum mais j'ai une question :

 comment evaluer le degrés d'une loi de student ?  ( ex : on suit une loi de student de degrès 10 VRAI/FAUX)

il y a 26 minutes, dwightkschrute a dit :

Hey pour le calcul du degré de libertés, tu as deux formules: 

>Echantillons indépendants: (n1 + n2) - 2 

>Echantillons appareillés: n-1 

=> n désigne les effectifs de l'étude 

 

Il te faut plus de précisions ? 

C’est super merci beaucoup
