QUE SIGNIFIE VARIANCE EN ANGLAIS
Variance
Dans la théorie des probabilités et les statistiques, la variance mesure à quel point un ensemble de nombres est étalé. Une variance de zéro indique que toutes les valeurs sont identiques. La variance est toujours non négative: une petite variance indique que les données ont tendance à être très proche de la moyenne et donc de l'autre, alors qu'une variance élevée indique que les données sont très répandues autour de la moyenne et l'une de l'autre. Une mesure équivalente est la racine carrée de la variance, appelée écart-type. L'écart-type a la même dimension que les données et, par conséquent, est comparable aux écarts de la moyenne. La variance est l'un des nombreux descripteurs d'une distribution de probabilité. En particulier, la variance est l'un des moments d'une distribution. Dans ce contexte, il fait partie d'une approche systématique pour distinguer les distributions de probabilité. Alors que d'autres approches de ce genre ont été développées, celles basées sur des moments sont avantageuses en termes de simplicité mathématique et de calcul.
définition de variance dans le dictionnaire anglais
