Reliable Valid Standardized

20 Standardization Uniform testing procedures
Meaningful scores by Comparison with performance of a pretested group. Consistency and objectivity of how tests are administered and scored.

21 Normal Curve = Symmetrical bell-shaped curve that describes the distribution of many physical and psychological attributes

Ex) If a subject were to take an intelligence test, then the consequent results should all be the same or at least approximately the same.
