This paper attempts to explore these amount 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: dependability, Validity, Estimates Introduction Across disciplines, competent researchers of ten not exclusively fail to report the reliability of their measures (Henson, 2001; Thompson, 1999), but also retrovert short of grasping the inextricable link between scale of measurement validity and effective research. At best, measurement error affects the ability to find significant results in virtuosos data.

At worst, measurement error can significantly damage the interpretability of retard or the function of a testing instrument. What is reliability? Reliability is the degree to which measures are salve from error and therefore collapse consistent results (i.e. the consistency of a measurement bit) . If a measurement device or procedure consi! stently assigns the same rack up to individuals 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 comparatively constant deviation scores of individuals across testing situations on the same, or parallel, testing instruments.
