Having peer review helps in determining the consistency of results in the area of study. On the other hand, reliability can be enhanced by conducting peer review among different people in the same field of study to find the best result and outcome that can be relied upon by all. Peer review help to compare the best approach to a given ailment and thus better drugs are provided to people (Gerrish & Lacey, 2010). In the field of medicine, the researcher should consult widely with peers to find solutions to health issues that affect people. Peer review is important because it helps to check the validity of any results derived from a research study. Thus, in a health and medicine field, it is important for researchers to undertake peer review of a given study. A peer can also be a person who shares qualifications or abilities with another researcher. A peer is a person who shares the same legal status in terms of education or even age. When the experiment is done, and the results are compared, they should indicate the same outcome.įor a research to be valid, the results should be verified by a peer in the same doctrine of study. In this regard, similar results are expected when using a common procedure. Validity measures how an instrument can measure a given characteristic in a research field accurately. Reliable data from a research study should be relevant to the problems that the researcher should solve to help in the decision-making process (Lippincott Williams & Wilkins, 2007). In this case, the experiments are done using the same research tools and procedures even if conducted by different researchers. This is achieved when several experiments are done using the same procedure. Reliability refers to the extent to which a given research project can give consistent results and outcome. External validity explains the depth of study and the level of generalization and comparison with research studies that different authors conduct. Internal validity is the design of conducting research and how the decision making process is undertaken to get the best results.
