Test Worthiness

Determined by an objective analysis of a test in four critical areas: (1) validity: whether or not it measures what it is supposed to measure; (2) reliability: whether or not the score an individual receives on a test is an accurate measure of his or her true score; (3) cross-cultural fairness: whether or not the score the individual obtains is a true reflection of the individual and not a reflection of cultural bias inherent in the test, and (4) practicality: whether or not it makes sense to use a test in a particular situation.

Cross-cultural Fairness

Statistical Formation

Refers to the process of organizing and summarizing data through the use of tables, graphs, and statistical measures to make the data understandable and usable.

Correlation

A statistical measure that indicates the extent to which two or more variables fluctuate together, showing the strength and direction of a relationship.
