August undefined, 2024

In probability and statistics, Student's t-distribution (or simply the t-distribution) is any member of a family of continuous probability distributions that arise when estimating the mean of a normally distributed population in situations where the sample size is small and the population's standard deviation is unknown. It was developed by English statistician William Sealy Gosset under the pseudonym "… WebbBienvenue @ Mathieu Robitaille qui est le nouveau représentant pour les secteurs de Laval-Joliette ainsi que l'Abitibi .
