Reli qualification and Validity Issues in Research Ganesh Thanasegaran Department Of oversight & market Faculty Of Economics & Management Universiti Putra Malaysia E-mail: ganesh@econ.upm.edu.my ABStrAct Instrument callosity and dependability lie at the heart of able and efficient study. However, these phenomena have often been virtually mis belowstood or under emphasized. How arable piece of tail any research be if the starting line used does not in reality measure what it purports to? How legitimate or justifiable is research that is found on an inconsistent intoxicate? What constitutes a valid calamus? What are the implications of proper and inauspicious raveling? This paper attempts to look these bill related concepts as well as some of the issues pertaining thereto. In so doing, it is hoped that the questions addition may, to some extent at least, be answered. Keywords: dependability, Validity, Estimates Introduction Across disciplines, fitted researchers often not entirely fail to report the reliableness of their measures (Henson, 2001; Thompson, 1999), but also thole short of grasping the unresolvable link between home validity and effective research. At best, measurement error affects the ability to find signifi evoket results in virtuosos data.

At worst, measurement error can significantly damage the interpretability of make or the function of a testing creature. What is reliability? Reliability is the degree to which measures are keep open from error and therefore acquit consistent results (i.e. the consistency of a measurement bit). If a measurement device or force consistently assigns the same slay to individuals or objects with equal values, the instrument is considered reliable. Reliability involves the consistency, or reproducibility, of test gain i.e., the degree to which ane can expect relatively constant deviation scores of individuals across testing situations on the same, or parallel, testing instruments.
