artefacts, statistical and methodological A statistical artefact is an inference that results from bias in the collection or manipulation of data. The implication is that the findings do not reflect the real world but are, rather, an unintended consequence of measurement error. When the findings from a particular study are deemed to be—at least in part—a result of the particular research technique employed (see RESEARCH DESIGN), rather than an accurate representation of the world, they are sometimes said to be a methodological artefact.
