content validity

Criterion related validity(predicitive validity)
measures future perfomance.
Constructive validity
is the degree to which a test measures what is claims, or purports to be measuring.
Reliability
the extent to which a test yields a consistent, reproducible measure of performance.
split-half reliability
test is split into two, each half is tested, if the scores are consistent, then the test is reliable (the closer the correlation is to +1, the more reliable)
Equivalent form reliability
the consistency of measurement based on the correlation between scores on two similar forms of the same test taken by the same subject.
test retest reliability
administering the same test twice over a period of time a group of individuals. The scores from Time 1 and Time 2 can be then correlated in order to evaluate the test for stability over time.
Standardization
The development of uniform procedures for administering and scoring a test, and the creation of norms (performance standards) for the test.
norms
performance standards
Z scores
how many standard deviations away from the mean
psychometricians
people who make tests (ETS, educational testing service makes the SAT).
power tests
the questions get increasingly difficult. Gauges what difficulty level you can get to.
Speed test
large number of questions asked in a short amount of time, insufficient time is given
goal: see how fast someone can solve problems
achievement tests
