English term or phrase: rational sub-grouping
***Rational sub-grouping*** is the process of putting measurements into meaningful groups to better understand the important sources of variation. Rational sub-grouping is typically used in process sampling situations when data is collected in real time during process operations. It involves grouping measurements produced under similar conditions.

For example, an equipment leasing business was trying to improve equipment turnaround time. They selected five samples per day from each of three processing centres. Each processing centre was formed into a subgroup.
When using sub-grouping, form subgroups with items produced under similar conditions. To ensure items in a subgroup were produced under similar conditions, select items produced close together in time.

Ich habe zwar etwas zur Bildung rationaler Untergruppen gefunden, das scheint mir aber nicht die gängige Bezeichnung für dieses Stichprobenverfahren zu sein. Es fällt wohl unter die systematischen Stichprobenverfahren: http://de.wikipedia.org/wiki/Systematische_Stichprobe

Hat jemand hier den passen Fachbegriff parat? Vielen Dank im Voraus!
