RELIABILITY‚ VALIDITY AND REPRESENTATIVE SAMPLE IN RESEARCH John and Webb (2002‚ p.148) distinguishes between validity and reliability‚ arguing that the first one is the extent to which a research is capable of measuring what it is supposed to be measuring and the second one is the extent to which a research delivers consistent results. Validity and reliability measurement instruments are free of bias and random error. Haynes and Heiby (2004‚ p.47) propose some questions addressing sampling adequacy
