Document Summary
Psyb32 lecture 4 october 2nd 2012. Mcq read chapters, go over important sections mentioned in class. Test-retest reliability some constructs don"t change (e. g. ) so they have high test-retest. Alternate form reliability giving different versions of the test eliminating practice effects. Internal consistency reliability ensuring all items in test are asking the same thing test this by splitting the number of questions in half and comparing them. Validity if a test is not reliable, it is not valid. Content validity need to measure as much of the construct as possible. The questions in a survey need to ask enough questions to get a full scope of what is trying to be understood. The test should measure all kinds of symptoms (if testing for a disorder). Criterion validity test needs to measure what we say it measures. Convergent validity results on 2 different tests for the same disorder, for example, should come to the same conclusion (should converge)
