In general, a large sample size decreases the probability of Type I (α) (false-positive) errors and increases the statistical power of the trial, i.e. decreases the probability of Type II (β) (false-negative) errors. A large sample size decreases the effect of random variation on the estimate of a treatment effect. In designing a study, the desired sample size can be calculated using a statistical formula based on the acceptable levels of α and β errors, the smallest difference between intervention groups considered clinically relevant, and the measurement variance. 2, record 1, English, - sample%20size

En règle générale, un vaste échantillon diminue la probabilité d’erreurs de type I(α), soit de faux positifs, et augmente la puissance statistique de l'essai, c'est-à-dire qu'il diminue la probabilité d’erreurs de type II(β), soit de faux négatifs. Un grand échantillon diminue l'effet de la variation aléatoire sur l'estimation d’un effet thérapeutique. Lors de la conception de l'étude, on peut calculer la taille de l'échantillon souhaitable à l'aide d’une formule statistique fondée sur les niveaux acceptables d’erreurs α et β, sur la plus petite différence entre les groupes expérimentaux considérées comme cliniquement pertinentes et sur la variance de la mesure. 2, record 1, French, - taille%20de%20l%26rsquo%3B%C3%A9chantillon
