RELIABILITY, VALIDITY, AND TRUSTWORTHINESS Reliability, Validity, and Trustworthiness Reliability, Validity, and Trustworthiness Introduction An evidence based practice in nursing researcher attempts to fragment and delimit phenomena into measurable or common categories that can be applied to all of the subjects or wider and similar situations (Winter, 2000). When you employ data triangulation methods, you end up with more comprehensive data and when it is supported in various research studies and in different types of research, then it is easier to analyse your data set and draw conclusions regarding the outcomes of your research. Depending on their philosophical perspectives, some qualitative researchers reject the framework of validity that is commonly accepted in more quantitative research in the social sciences. Validity should be considered in the very earliest stages of your research, when you decide how you will collect your data. If the results are generalisable other researchers can interpret findings and apply them to broader contexts. Quantitative research includes reliability measures where the researcher must prove that the process and the results have replicable outcomes. Transferability refers to whether results transfer to situations with similar characteristics. Then read this to find out how to do it to a high standard, Researchers, of necessity, must be aware of the need for ethical considerations in research. Internal validity utilises three approaches (content validity, criterion-related validity and construct validity) to address the reasons for the outcome of the study. In contrast to transferability, quantitative researchers use the method of external validity to establish trustworthiness.

Validity and reliability are the watch words which underpin all research: In the past the humanities were not really concerned about these constructs, but now all research demands rigour and reliability and validity in quantitative research as well as qualitative research is of paramount importance. Researchers, for this reason, have a duty to the scientific community to report their methodology, results and findings honestly. Validity Reliability Quantitative. This measures the degree of agreement of the results or conclusions gotten from the research questionnaire with the real world.

If responses become more consistent across larger numbers of samples, the data becomes more reliable. Validity and reliability are two important aspects in order to approve and validate the quantitative research. Validity shows how a specific test is suitable for a particular situation. Written in an accessible style using simple and direct language, Communication Research Statistics guides students through the statistics actually used in mo In quantitative research, you have to consider the reliability and validity of your methods and measurements.. Validity tells you how accurately a method measures something. Validity test is divided into three types: criterion- related, content, and construct validity (Creswell, 2005).

Member checking, or testing the emerging findings with the research participants, in order to increase the validity of the findings, may take various forms in your study. Getting others who are entirely removed from your research to test the survey is a great workaround – this will also allow you to check their responses do indeed answer or confirm the underlying hypothesis. Things are slightly different, however, in Qualitative research.. + input dud data just to get it over with External validity is used to generalize from the research sample to the larger population.
