One sample t-test is a kind of Student's t-test which evaluates if a given sample can be reasonably assumed to be taken from the population. The test compares the sample statistic (m) to the population parameter (M). The one sample t-test is the small sample analog of the z test, which is suitable for large samples.

Le test de t sur un échantillon est une sorte de test t de Student qui évalue si un échantillon donné peut être raisonnablement supposé être tiré de la population. Le test compare la statistique de l'échantillon (m) au paramètre de population (M). Le test t d'un échantillon est l'analogue pour les petits échantillons du test z, qui convient aux gros échantillons.
