The challenges to gain the validity through out the entire research were less. The research question has to be reworded to gain the specific answers the research need from the sample. This also did affect that data from which the sample may be miss lead or confuse by the miss wording.
Reliability and Validity in Qualitative Studies By Marilyn Simon and Jim Goes Discussions about reliability and validity are ubiquitous in quantitative research, but these essential elements of confidence in the research often receive less attention and scrutiny in qualitative studies.
In qualitative research, validity—or trustworthiness— and reliability—or consistency— are discussed in terms of the credibility, transferability, dependability, and confirmability of the instrumentation and results of the study. It is important to understand that dependability is to qualitative research as reliability is to quantitative research.
There must be credibility in order to have dependability. The qualitative researcher needs to explain how dependability and credibility are assured and in the research methodology and documented in the data that are collected.
To assure credibility internal validity you can describe appropriate strategies such as triangulation, prolonged contact, member checks, saturation, reflexivity, and peer review. Dependability the qualitative counterpart to reliability can be established through audit trails and triangulation.
Confirmability the qualitative counterpart to objectivity is established through reflexivity or intra- or inter-coder reliability, where applicable. Providing participants a copy of the transcribed notes from audio recordings enables them to review detailed interview responses member checkingand verify the interpretive accuracy.
This increases reliability Carlson, Harvey has suggested a continuous member-checking loop as part of the reliability process.
Validity in qualitative research indicates consistency and trustworthiness regarding activities and events associated with the phenomenon as signified by the study results explored in the research Golafshani, Validity and reliability increase transparency and decrease opportunities to insert researcher bias in qualitative research Singh, The researcher must ensure reliability and validity of the study based on the ability to maintain neutrality, and trustworthiness Golafshani, Quality in qualitative studies: The case of validity, reliability and generalization.

Centers about consumers’ skills and challenges so that appropriate services and supports can be obtained. The second is the need to assess the outcomes of the services provided to consumers. statewide evaluation of the reliability and validity of the revised CDER was conducted in , demonstrating that it is a reliable and valid.
Define validity, reliability, falsifiability, generalizability, and reproducibility as they relate to quantitative research. Explain the importance of each in a quantitative study. If the results of quantitative research are to be considered useful and trustworthy, there are several key issues that must be considered and addressed as part of the experimental design and .
reliability estimate of the current test; and m equals the new test length divided by the old test length. For example, if the test is increased from 5 to 10 items, m is 10 / 5 = 2.
