Criterion measurement is not based on what statistical model?

The concept of criterion measurement focuses on evaluating outcomes or behaviors against a predefined standard or criterion rather than relying on a statistical model like the normal distribution.

In criterion measurement, the assessment is not concerned with how a score compares to a broader population represented by a bell curve. Instead, it emphasizes whether an individual meets a specific benchmark or criterion that has been established as indicative of successful performance or understanding. This approach is more about meeting specific goals and less about distributional properties or population norms.

While other choices, such as standard deviations from the mean, relative comparisons to the population, and average score calculations, often rely on statistical models like the normal distribution for their interpretations and applications, criterion measurement is fundamentally different as it measures against a clear standard, independent of the population's distribution. This distinction reinforces that criterion measurement assesses whether specific performance standards are achieved rather than fitting into a normative framework.
