gruppierte

Gruppierte is the attributive form of the German past participle of the verb gruppieren, meaning to group or categorize. It describes items that have been arranged into groups. As an adjective it takes the standard German endings, for example: der gruppierte Datensatz, die gruppierte Liste, die gruppierten Daten. The form can also appear as a simple past verb form: ich gruppierte die Daten, er gruppierte die Listen.

In statistics and data processing, gruppierte Daten are data that have been binned into discrete classes or intervals. This grouping supports the creation of frequency distributions, histograms, and summarized representations. It contrasts with ungegruppierte Daten or rohe Daten, which are observed individually. The choice of class width and class boundaries is a key aspect of the grouping process and is often performed with software tools. The term is common in German-language statistical textbooks and software documentation.

Grammatical notes: The attributive adjective gruppierte takes endings according to gender and case (der gruppierte Datensatz, die gruppierte Liste, die gruppierten Daten). The corresponding past participle used with the auxiliary haben is gruppiert (Ich habe die Daten gruppiert). The simple past forms, such as ich gruppierte, er gruppierte, are also correct in narrative contexts. In everyday language, gruppieren is most often encountered in discussions of data organization, classification, and data visualization.
