Exam 5: Reliability

A psychologist administers a test and the test-taker scores a 52.If the cut-off score for eligibility for a particular program is 50,what index will best help the psychologist determine how much confidence to place in the test-taker's obtained score of 52?

If a test is homogeneous

Stanley (1971)wrote that in classical test theory,a so-called "true score" is "not the ultimate fact in the book of the recording angel." By this,Stanley meant that

If items from a test are measuring the same trait,estimates of reliability yielded from split-half methods will typically be ________ as compared to estimates from KR-20.

Test-retest estimates of reliability are referred to as measures of ________,and split-half reliability estimates are referred to as measures of ________.

As the reliability of a test increases,the standard error of measurement

In general,approximately what percentage of scores would be expected to fall within two standard deviations above or below the standard error of measurement of the "true score" on a test?

A confidence interval is a range or band of test scores that

Which source of error variance affects parallel- or alternate-form reliability estimates but does not affect test-retest estimates?
