QUE SIGNIFIE FALSE NEGATIVE EN ANGLAIS
Erreurs type I et type II
Dans les statistiques, une hypothèse nulle est une affirmation selon laquelle la chose étudiée ne produit aucun effet ou ne fait aucune différence. Un exemple d'hypothèse nulle est l'énoncé «Ce régime n'a aucun effet sur le poids des personnes». Habituellement, un expérimentateur encadre une hypothèse nulle dans l'intention de le rejeter: c'est-à-dire, l'intention d'exécuter une expérience qui produit des données qui montre que la chose à l'étude fait une différence. Une erreur de type I est le rejet incorrect d'une véritable hypothèse nulle. En ce qui concerne l'hypothèse non nulle, elle représente un faux positif. Habituellement, une erreur de type I conduit à conclure qu'un effet ou une relation supposée existe quand en fait il ne l'est pas. Des exemples d'erreurs de type I incluent un test qui montre un patient qui a une maladie lorsque, en fait, le patient n'a pas la maladie, une alarme incendie disparaît indiquant un incendie alors qu'il n'y a pas de feu ou une expérience indiquant qu'un traitement médical Devrait guérir une maladie, en fait, elle ne le fait pas. Une erreur de type II est l'échec à rejeter une hypothèse nulle nulle. En ce qui concerne l'hypothèse non nulle, elle représente un faux négatif.
