internal consistency is which type of test?

internal consistency test

do all of the questions measure the same thing?

which test is the cronbach alpha used for

reliability

measure of consistent results

validity

how well a test measures what is trying to measure

face validity

does a question look like it is measuring a specific variable? eg.does “I sleep well” look like it is measuring depression

content validity

do the questions target all factors related to the key concept? eg. driving test= road signs, parking, rules, safety procedures

criterion validity

does the question relate to things it SHOULD relate to (two types)

convergent validity (type of criterion)

how closely a test correlates with another test for the same thing (old trig test vs new trig test)

predictive validity (type of criterion)

does a question predict expected outcomes? (high depression predictive of people who do drugs, skip class, etc.)

discriminant validity

high if your measure for something does not correlate with a random construct. eg. high depression with small shoe size
