- niveau 1 niveau 2 niveau 3
Descriptif
Several samples are extracted, the means of which are calculated. The distribution of these means is represented graphically. It shows that the means of samples (sufficiently large) extracted from a population are distributed according to an average rule. This distribution is centered on the average of the population from which the samples are extracted. This is the basis of the Limit Central Theorem (TCL), which is deliberately not stated but only suggested. The notion of the p-value is then explained graphically.
