New reponses 4 and 5 When conducting research its important to know if the sources used are reliable and valid. According to Phelan & Wren (2005) reliability refers to the degree to which an assessment tool produces stable and consistent results and validity refers to how well a test measures what it is purported to measure. Reliability is used in dentistry everyday when assessing our patient’s periodontal health. We use a special instrument to measure the gums that’s gives reliable results every time because of the 1mm marks. Validity is also used in our office daily when we take x-rays on our patients. Say we used our periodontal instrument to measure the gums; we can use the x-rays to measure the bone level. In the bone level is low, our measurements will be high and if our bone levels are healthy and high, our periodontal measurements will be low. Phelan, C., Wren, J. (2005). Exploring Reliability in Academic Assessment. Retrieved from https://chfasoa.uni.edu/reliabilityandvalidity.htm 5. Validity and reliability are concepts that help when measuring properties of a survey, test, questionnaire or anything that is measure. Definitions are, “Validity refers to the extent to which a procedure measures what it is supposed to measure” (Neutens & Rubinson, 2014, pg. 167). “Reliability refers to the stability of the instrument” (Neutens & Rubinson, 2014, pg. 167). Reliability means that the research process has been repeated several times and the results continue to be similar. So when the information is reliable the information can be valid. A good example of validity and reliability at my workplace is the CBC machine/SYSMEX. Our CBC machine is used constantly, and to measure reliability we repeat our samples to make sure the information is correct. When the results are constantly similar, we valid the CBC results for each patient. As well we validate the machine to be accurate. Reference Neutens, J. J., & Rubinson, L. (2014).

The constant, ever changing medical field coextends with research methods in health sciences. Researchers use certain methods such as experimental, survey, evaluation, qualitative, clinical, comparative, and analytic epidemiology (Neutons & Rubison, 2014). Experimental research relates to a study in which the researchers control one or more variables in the experiment to determine results. Survey research methods describe and reveal results of an occurrence, provide descriptions of conditions while comparing and contrasting the relationships of the variables. Evaluation research provides a method of assessment from collected evidence derived from a sample population in which the conclusions relay effectiveness, merit, and success of the process/program studied. Qualitative research is a method of gathering and analyzing numerical or quantitative data. Many regulatory organizations across the na ...
