1. Which is closest to the definition of reliability?
2. Reliability is a prerequisite for validity.
3. To determine the reliability of a measure, you would test participants on that measure, then
4. A reliable measure would have a test-retest coefficient above +0.70.
5. If a measure has a test-retest correlation coefficient of +.90, 10% of the variability in the scores are due to random error.
6. If interobserver reliability is .60, test-retest reliability cannot be above .60.
7. If test-retest reliability is .90, you should calculate your measure´s interobserver reliability.
8. Low internal consistency may be due to random error due to participants.
9. Editing and deleting unclear questions from a measure will tend to increase its internal consistency.
10. An odd-even correlation of .60 indicates that the measure is internally consistent.
11. Split-half reliability is a good index of the extent to which random observer error affects your measure.
12. All reliability coefficients are essentially the same.
