Normative Data

Data from a reference population that establishes a baseline distribution for a score or measurement, and against which the score or measurement can be compared. Normative data is typically obtained from a large, randomly selected representative sample from the wider population. Example, "ideal" range of motion for a goniometric assessment of a joint is established using normative data collected from various research studies.
