The values for reliability coefficients range from 0 to 1.0. A coefficient of 0 means no reliability and 1.0 means perfect reliability. Since all tests have some error, reliability coefficients never reach 1.0. … 80, it is said to have very good reliability; if it is below .

What is reliability method?
Some examples of the methods to estimate reliability include test-retest reliability, internal consistency reliability, and parallel-test reliability. Each method comes at the problem of figuring out the source of error in the test somewhat differently.
What is the best definition of validity?
Validity is the extent to which a concept, conclusion or measurement is well-founded and likely corresponds accurately to the real world. The word “valid” is derived from the Latin validus, meaning strong.
