Norms and the Normal Curve
Captions available
The idea
Norms are the distribution of scores from the standardization sample, and intelligence scores are scaled to a normal curve.
In practice
Scores are set so that the population average is one hundred and most people fall within fifteen points of it.
Where people slip
The distribution is imposed by scoring, not discovered. The curve is a design choice made explicit.
