VALIDITY OF QUANTITATIVE RESEARCH

VALIDITY 1 VALIDITY OF QUANTITATIVE RESEARCH Recall the basic aim of science is to explain natural phenomena. Such explanations are called theories (Kerlinger, 1986, p. 8). Theories have varying degrees of truth. VALIDITY is the best approximation to the truth or falsity of propositions (Cook & Campbell, 1979). VALIDITY is at best approximate or tentative since one can never know what is true. At best, one can know what has not yet been ruled out as false (Cook & Campbell, 1979, p. 37).
