If you enter all of these commands into R you should have noticed that the last p value is not correct. Dans un test statistique, la valeur-p (en anglais p-value pour probability value), parfois aussi appelée p-valeur, est la probabilité pour un modèle statistique donné sous l'hypothèse nulle d'obtenir une valeur au moins aussi extrême que celle observée. L'usage de la valeur-p est courant dans de nombreux domaines de recherche comme la physique, la psychologie, l'économie et les sciences de la vie. gilmer high school football ga
