The test’s confidence level can be selected in W column. Single outliers should be removed first. Do not remove more data than reasonable.

According to VIM3 [1], a method is: a “generic description of a logical organization of operations used in a measurement” (Entry 2.5) (e.g. standard addition method or gas-chromatography) …therefore, methods cannot be validated because are too general. The detailed description of the analytical methodology, subject to validation, is a procedure: Measurement procedure (Entry 2.6): “detailed Read more about Procedure (not method…) validation![…]
A measurement result is usually expressed as a (“measured quantity value” ± “measurement uncertainty”). The measured quantity value aims at estimating the “true” quantity value of a measurand (VIM3: Entry 2.10). On the other hand, the measurement uncertainty is evaluated “based on the information used” (VIM3: Entry 2.26) since there is no “true” value for Read more about The measurement uncertainty was…?![…]
