3.What is an example of Criterion validity?
a.ex. A driving test, licensing test, pilot test
4.What is Criterion Contamination
a. When your test’s criterion is influenced by a predictive
measure and is not balanced. For example, if you are taking a pilot test
they measure processing time, vision, and skills. If there are 100
questions and 45 of those questions are questions about vision, the test
is unbalanced and the criterion is now contaminated
5.What is criterion related validity?
“Minimum competency”. For example, on the drivers test the hi+–
ghest score you can get is a perfect 26 but you need a score of AT
LEAST 19 to pass and get your license.
6.What is Item validity Index?
It is for criterion related validity and measures how well each item
is assessing what it is supposed to be assessing. Ex. how well does
question 16 on the pilot exam assess visual speed
7. What is Expectancy table?
a.what do you need, how many items, what are the categories
8.What is Expectancy data?
a.The rate of which you expect something to occur
9.What is Item difficulty index used for?
To discriminate between low and high scores (content validity)
Validity coefficient of the test
10. What is Construct Validity supposed to do?
It is supposed to underlay all the validities
11.What is construct validity based on?
Theory based. For example in the case of “personality or
intelligence” they are not something that you can concretely see,
however you can develop different theories of personality and
intelligence to measure it.
12. What is Construct validity? (theory)
a. how well does this test reflect the theory its based Ex.
Intelligence tests
13. What are the 3 types of tests?

WASI- short intelligence test, use with somebody with extreme
intelligence deficit
WIAT- preschoolers to age 50 yrs
WPPSI- new tests for fluid reasoning and processing speed
21.What is Standford Binet 5th ed. Good for?
a. – good for evaluating giftedness for people who are very low
and need intelligence intervention. Routing procedure- vocab
test first, this will determine other tests given -Most items
not timed

23. What are the two Norms?
