Minitab: Indicates the number of independent pieces of information involving the response data needed to calculate the sum of squares.

ISO 3534: Number of terms in a sum minus the number of constraints on the terms of the sum.

6 sigma: Degrees of freedom (df) of a test statistic equals the number of independent observations in a sample minus the number of population parameters that are estimated from the sample observation.

ISO 3534: Nombres de termes d'une somme moins le nombre de contraintes sur les termes de la somme.

FD V01-000: Plus petite concentration de l'analyte pouvant être détectée, mais non quantifiée, dans les conditions expérimentales décrites de la méthode.

ICH: It is the lowest amount of analyte in a sample which can be detected but not necessarily quantitated as an exact value.

6 sigma: The distance between a data point and the mean. Deviation measures and describes the variation in a set of data.

6 sigma: Numeric data that is not capable of being meaningfully subdivided into more precise increments.

IATF 16949: Donnée: série d'observations selon un jeu de conditions qui sont soit des variables (valeur numérique, mesure…) soit des variables discrètes (attributs, ex: bon/mauvais, automatique/manuel).

Minitab : to summarize numeric data with a variety of statistics such as the sample size, mean, median, and standard deviation.
