Question 7

What does a reliability coefficient of 0.90 mean?

Answer 7

An acceptable reliability coefficient must not be below 0.90, less than this value indicates inadequate reliability. For instance, r =. 90 on a test means that 90% of the test score is accurate while the remaining 10% consists of standard error

Question 8

What Is Test-Retest Reliability?

Answer 8

0.9 and greater: excellent reliability.
Between 0.9 and 0.8: good reliability.
Between 0.8 and 0.7: acceptable reliability.
Between 0.7 and 0.6: questionable reliability.
Between 0.6 and 0.5: poor reliability.
