ICH: It is the ability to assess unequivocally the analyte in the presence of components which may be expected to be present. Typically these might include impurities, degradant, matrix, identification, purity tests, and assay.

Definition
6 sigma: Standard Operating Procedure (SOP) is an organized way of disseminating information, regarding actions, responsibilities and preventive measures associated with process variables. SOP's ensure a predictable output and reduce the chances for unintended variation

Definition
Minitab: The sum of squared distances. SS Total is the total variation in the data. SS Regression is the portion of the variation explained by the model, while SS Error is the portion not explained by the model and is attributed to error. SS Total= SS Regression + SS Error
Standard deviation (s or σ)

by GUENNOUNI, Nathalie
Definition
Minitab : The standard deviation is most common measure of dispersion, or how spread out the data are from the mean. The greater the standard deviation, the greater the spread in the data. The symbol σ (sigma) is often used to represent the standard deviation of a population, while s is used to represent the standard deviation of a sample
