For example, in an experimental setup, make sure all participants are given the same information and tested under the same conditions. However, as humans are inherently subjective creatures it is not possible to study them in the same way sciences are studied. Validity is whether the research measure what it intends to and how accurate the data is (Golafshani, 2003). Students who got failed in the pre-final exam are likely to get passed in the final exams; they might be more confident and conscious than earlier. According to Wilson (2010) reliability issues are most of the time closely associated with subjectivity and once a researcher adopts a subjective approach towards the study, then the level of reliability of the work is going to be compromised. A valid measurement is generally reliable: if a test produces accurate results, they should be. For example, if you are conducting interviews or observations, clearly define how specific behaviours or responses will be counted, and make sure questions are phrased the same way each time. Validity is harder to assess, but it can be estimated by comparing the results to other relevant data or theory. What Scientific process is used in all research?
