Quantitative research relies on the reliability and validity of its data. Week 6: Quantitative Research Designs, Continued No discussion about quantitative research design would be complete without mention of validity and reliability. Each qualitative research is unique, and as such, the application of such factors as measures of validity however remain subjective. Is sufficient information given to interpret the results of data analysis? (Sometimes there is no explicitly identified theoretical or conceptual framework; in addition, many “nursing” research studies draw on a “borrowed” framework, e.g., stress, medical pathology, etc.). If there is low validity in a study, it usually means that the research … Is there evidence that the author critiqued the literature or merely reported it without critique? Face validity is considered to be as subjective and informal assessment. Guba and Lincoln (1981) stated that while all research must have “truth value”, “applicability”, “consistency”, and “neutrality” in order to be considered worthwhile, the nature of knowledge within the rationalistic (or quantitative) paradigm is different from the knowledge in naturalistic (qualitative) paradigm. Validity in research refers to the extent researchers can be confident that the cause and effect they identify in their research are in fact causal relationships.

Internal validity asserts that variations in the dependent variable originate from variations in the independent variable(s) – not from other confounding factors. Taking all these varying perspective together validity in qualitative research can be defined as the accuracy in the account of the participants to their realities of the social phenomena and its credibility to them. (2010). Yuan, S.-C., Chou, M.-C., Hwu, L.-J., Chang, Y.-O,, Hsu, W.-H., & Kuo, H.-W. (2009). Validity is defined as the extent to which a concept is accurately measured in a quantitative study. There are attempts to establish validity in qualitative research, for instance, Silverman (2006) Interpreting Qualitative Data has made such an attempt, and clearly argues, ‘we should not assume that techniques used in quantitative If research has high validity, that means it produces results that correspond to real properties, characteristics, and variations in the physical or social world. )Validity in Quantitative Research Designs Essay. Epub 2015 May 15. The second measure of quality in a quantita- tive study is … Qualitative Validity 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.

However, the concept of determination of the credibility of the research is applicable to qualitative data. What instruments and/or other measurement strategies were used in data collection? Moskal & Leydens (2002) defined the validity as “the degree to which the evidence supports that the interpretations of the If there is low validity in a study, it usually means that the research design is flawed and the results will be of little or no value. Describe the method and criteria. What are the hypotheses (or research questions/objectives) of the study? High reliability is one indicator that a measurement is valid. 2015 Jul;18(3):66-7. doi: 10.1136/eb-2015-102129.

Dealing with different types of validity is what makes establishing validity in qualitative research very difficult. Recognize the importance of combining qualitative and quantitative research to get the best result. Information about most research topics is available online, and this aids in boosting the validity of primary quantitative data as well as proving the relevance of previously collected data.

In quantitative research, this is achieved through measurement of the validity and reliability.1 Validity is defined as the extent to which a concept is accurately measured in a quantitative study. It can be specified that “internal validity refers to how the research findings match reality, while external validity refers to the extend to which the research findings can be replicated to other environments” (Pelissier, 2008, p.12). An intervention program to promote health-related physical fitness in nurses.

Validity in Quantitative Research Designs. What is Validity and Reliability in Qualitative research? ), Are the conclusions and implications drawn by the author warranted by the study findings? If the results are accurate according to the researcher's situation, explanation, and prediction, then the research is valid. How might this research inform your practice? The construct is the initial concept, notion, question or hypothesis that determines which data is to be gathered and how it is to be gathered. If a method measures what it claims to measure, and the results closely correspond to real-world values, then it can be considered valid. In essence, it is how well a test or piece of research measures what it is intended to measure. One measure of validity in qualitative research is to ask questions such as: “Does it make sense?” and “Can I trust it?” This may seem like a fuzzy measure of validity to someone disciplined in quantitative research, for example, but in a science that deals in themes and context, these questions are important.

Examples of Threats to Internal Validity in Quantitative Research Work. Reliability refers to the extent to which the same answers can be obtained using the same instruments more than one time. In quantitative research testing for validity and reliability is a given. How might a proposed change in practice trigger changes in other aspects of practice?Validity in Quantitative Research Designs Essay. If a research problem is truly significant, the results need to be confirmed with additional research; in addition, if a reader wishes to design a study using a different sample or correcting flaws in the original study, a complete description is necessary. Are the research findings appropriate to your practice setting and situation? Yuan, S., Chou, M., Hwu, L., Chang, Y., Hsu, W., & Kuo, H. (2009).

Validity in research refers to the extent researchers can be confident that the cause and effect they identify in their research are in fact causal relationships. However some qualitative researchers have gone so far as to suggest that validity does not apply to their research even as they acknowledge the need for some qualifying checks or measures in their work. Validity refers to how accurately a method measures what it is intended to measure. Is there an integrated summary of the current knowledge base regarding the research problem, or does the literature review contain opinion or anecdotal articles without any synthesis or summary of the whole? Use your results to increase the validity of your data. Similarly, the procedures of establishing validity essentially depend on the philosophical paradigm of the study. For example, a survey designed to explore depression but which actually measures anxiety would not be considered valid.
