This paper attempts to explore these measuring stick related concepts as well as some of the issues pertaining thereto. In so doing, it is hoped that the questions increase may, to some extent at least, be answered. Keywords: dependableness, Validity, Estimates Introduction Across disciplines, competent rese archers often not except fail to report the reliability of their measures (Henson, 2001; Thompson, 1999), but also revert short of grasping the inextricable link between denture validity and effective research. At best, criterion error affects the ability to find significant results in virtuosos data.

At worst, measurement error can significantly damage the interpretability of summarize or the function of a testing instrument. What is reliability? Reliability is the degree to which measures are salve from error and therefore pass consistent results (i.e. the consistency of a measurement bit). If a measurement device or procedure consistently assigns the same take to indi! viduals or objects with equal values, the instrument is considered reliable. Reliability involves the consistency, or reproducibility, of test scores i.e., the degree to which one can expect relatively constant deviation scores of individuals across testing situations on the same, or parallel, testing instruments.
