The objective researcher is distant so that the researcher is not influenced by the participants, and does not influence the study. Inquiry audit for a researcher auditor to examine the process of the study and determine its acceptability to the dependability of the study. Validity within quantitative research is a measure of how accurately the study answers the questions and hypotheses it was commissioned to answer. You will also consider the ethical implications of designing quantitative research. This method consists of researchers asking a colleague or another person to look over the study for credibility and determine if the results seem to align from the data. In quantitative studies, there are two broad measurements of validity – internal and external. Next, explain a strategy to mitigate each of these threats. Multiple theories are examined because theories can be interrelated, and findings could result in a function of the similarity of theories. The researcher auditor looks into the data, findings, interpretations, and recommendations and looks into whether the study is supported by data and is trustworthy. There are four main types of validity: Credibility is one method used by qualitative researchers to establish trustworthiness by examining the data, data analysis, and conclusions to see whether or not the study is correct and accurate. Validity in qualitative research can also be checked by a technique known as respondent validation. Dealing with different types of validity is what makes establishing validity in qualitative research very difficult. Determining validity in quantitative research (Source: Drost, 2011; p117) The entire research process should establish validity. In qualitative research, validity depends on unobtrusive measures, respondent validation, and triangulation. The method of using a reflexive journal can also be useful for quantitative researchers because they can provide information about methodological decisions made and reasons for choosing certain methods, instruments, and data analyses of the study. Next, explain a strategy to mitigate each of these threats. 3. Explain strategies to mitigate threats to internal validity and external validity in quantitative research. Equivalence and stability estimate is another way to examine reliability by administering one form of an instrument and then a second form of the instrument after a certain amount of time to the same group of individuals. Traditionally, the establishment of instrument validity was limited to the sphere of quantitative research. 83458, posted 24 Dec 2017 08:48 UTC. Research validity can be divided into two groups: internal and external. It is important for quantitative researchers to remember the following possible threats to internal validity: history, selection, maturation, pretesting, instrumentation, treatment replications, subject attrition, statistical regression, diffusion of treatment, experimenter effects, and subject effects. The service is geared toward eliminating any mistakes and rather enhancing better quality. Finally, explain what it means for a research topic to be amenable to scientific study using a quantitative approach. Negative case analysis is used to show that not all the data will provide the same result. Validity. Most broadly, validity refers to meaningfulness and reliability refers to consistency. Follow these simple steps to get your paper done. Under such an approach, validity determines whether the research truly measures what it was intended to measure.

Help in Schoolwork has stood as the world’s leading custom essay writing services providers. In other words, validity is the extent to which the instrument that was selected actually reflected the reliability of the constructs that were being measured. Then, identify a potential ethical issue in quantitative research and explain how it might influence design decisions. Synonyms to explain reliability and validity are many, and in qualitative research these include credibility, transferability, and dependability. Threatens INTERNAL validity when the treatment being applied to one group spills over to contaminates another group. You will get a personal manager and a discount. The following are procedures qualitative researchers can use to increase credibility in qualitative studies: 1.
