oversample
/ˈoʊvərˌsæmpəl/
Definition
To include a larger proportion of a specific subgroup in a survey than exists in the general population to ensure there is enough data for meaningful analysis.
Etymology
Derived from the English prefix 'over-' (meaning 'in excess' or 'to an excessive degree') combined with 'sample' (a subset of a population). It emerged in the context of statistics to describe the practice of deliberately increasing the representation of minority or specific segments within a study group.
In the news
The researchers utilized a non-probability oversample to ensure they had sufficient data on Michigan adults specifically, allowing for a more detailed analysis than a smaller, representative sample might provide.
