18. Modern WAIS test (2008 Edition) have 15 subtests

19. Constructive Intelligence Test Should be ….
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
