Detailed explanation-1: -As a general rule, a reliability of 0.80 or higher is desirable for instructor-made tests. The higher the reliability estimated for the test, the more confident one may feel that the discriminations between students scoring at different score levels on the test are, in fact, stable differences.
Detailed explanation-2: -For example, if your scale is off by 5 lbs, it reads your weight every day with an excess of 5lbs. The scale is reliable because it consistently reports the same weight every day, but it is not valid because it adds 5lbs to your true weight. It is not a valid measure of your weight.
Detailed explanation-3: -A high inter-rater reliability coefficient indicates that the judgment process is stable and the resulting scores are reliable.
