Underprøver
Underprøver is a term used in Scandinavian statistical and research contexts to denote subsamples drawn from a larger population or data set for analysis. The form is the plural of underprøve, combining the prefix under- with prøve meaning “sample” or “test.” The term is not uniformly standardized and may be encountered primarily in Norwegian and Danish methodological writings rather than in formal statistics handbooks.
In practice, an underprøver is selected to perform preliminary analyses, calibrate measurement instruments, or test hypotheses
Analysts use underprøver to estimate population parameters, assess model assumptions, or validate data collection procedures before
