The standard deviation of a finite population ... generally denoted by the Greek letter [sigma].  1, record 1, English, - population%20standard%20deviation

In context, the population standard deviation is often referred to as simply "standard deviation".  6, record 1, English, - population%20standard%20deviation

for "standard deviation" : A great deal of confusion has been introduced into statistical literature by the many different expressions which have been used for the standard deviation and the simple derivatives of it. (...) The term "standard deviation" is now almost universally accepted (...). "Mean error" (Gauss), "mean square error" and "error of mean square" (Airy) have all been used to denote the standard deviation. The standard deviation is not to be confused with "standard error".  2, record 1, English, - population%20standard%20deviation

«écart quadratique moyen» : Du point de vue sémantique, on pourrait croire qu’"écart quadratique moyen" est synonyme de "variance"; cependant, l’usage veut qu’"écart quadratique moyen" soit synonyme d’"écart-type" et que "variance" se définisse comme étant "l’écart quadratique élevé au carré".

Record number: 3, Textual support number: 1 OBS

1. An unbiased estimator of the variance of a probability distribution obtained from a sample of n independent observations is obtained by dividing by n-1 the sum of the squares of the deviations of the observed values from the arithmetic mean of this sample. 2. The positive square root of the unbiased estimator of the variance is often used as an estimator of the standard deviation. However, it ought to be noted that this estimator is not unbiased.  3, record 3, English, - estimation%20of%20the%20variance%20of%20a%20population

1. Un estimateur sans biais de la variance d’une loi de probabilité à partir d’un échantillon de n observations indépendantes s’obtient en divisant par n 1 la somme des carrés des écarts des valeurs observées par rapport à la moyenne arithmétique de cet échantillon. 2. La racine carrée positive de l'estimateur sans biais de la variance est souvent utilisée comme estimateur de l'écart-type. Il faut noter pourtant que cet estimateur n’ est pas sans biais.  3, record 3, French, - estimation%20de%20la%20variance%20d%26rsquo%3Bune%20population
