Readings for february 14th chapter 3 (p. 71-92) Inter-rater reliability measures the degree to which two independent observers or judges agree. Test-retest reliability measures the extent to which people being observes twice or taking the same test twice, perhaps several weeks or months apart, score in generally the same way. Alternate-form reliability using two forms of a test where there is concern that people will remember their answers from the first test and aim merely to be consistent. The extent to which scores on the two forms of the test are consistent. Internal consistency reliability assesses whether the items on a test are related to one another. Validity: extent to which a measure fulfills its intended purpose. Content validity is the extent to which a measure adequately samples the domain of interest. Criterion validity is evaluated by determining whether a measure is associated in an expected way with some other measure.
