Reliability and Validity Issues of research reliability and validity need to be addressed in methodology chapter in a concise manner. Reliability refers to the extent to which the same answers can be obtained using the same instruments more than one time. Reliability is a necessary ingredient for determining the overall validity of a scientific experiment and enhancing the strength of the results. Debate between social and pure scientists, concerning reliability, is robust and ongoing. Assessment validity is a bit more complex because it is more difficult to assess than reliability. There are various ways to assess and demonstrate that an assessment is valid, but in simple terms, assessment validity refers to how well a test measures what it is supposed to measure. Reliability and validity are two desirable qualities of any measurement procedure or instrument.

These are used to evaluate the research quality. Both these concepts imply how well a technique, method or test measures some aspect of the research. While reliability deals with consistency of the measure, validity deals with accuracy of the measure. Validity refers to the degree to which a study accurately reflects or assesses the specific concept that the researcher is attempting to measure. While reliability is concerned with the accuracy of the actual measuring instrument or procedure, validity is concerned with the study's success at measuring what the researchers set out to measure.

In this Exploring Reliability and Validity Assignment, you will analyze the psychometrics provided from the Values and Motives Questionnaire (VMQ), addressing 1) the type of reliability and validity used; 2) the areas of concern/strength for the Cronbach alpha coefficients; 3) how sample size and nature of the population may influence the constructs that the test attempts to measure Reliability and validity are significant elements of any assessment tool. However thoroughly developed the tools are, if they are not valid or reliable, the research is doomed to fail.
