Fill in the blank: In_____errors,issues of reliability stem from the actual subjects of the experiments. They classified these criteria into primary and secondary criteria. Results are compared and correlated with the initial test to give a measure of stability. Stability reliability (sometimes called test, re-test reliability) is the agreement of measuring instruments over time. Reliability and validity are very important because without them, research would not be considered valuable and could lead to false claims or misinformation.
