The concept of reliability and validity are interrelated. . In the example in table 2. Saunders et al 2007 Further, Johnson and Clark 2006 argues that the most important issue is not which philosophical space the research occupies but on how well the research is reflected and defence against the alternatives the researcher could have adopted. Data collection methods are simply how the information is gathered.
The research problem and the purpose of the study assist the researcher in identifying the group to involve in the study. Qualitative researchers rely — implicitly or explicitly — on a variety of understandings and corresponding types of validity in the process of describing, interpreting, and explaining phenomena of interest. Reliability and Validity Reliability and validity are important with any kind of research. Research demonstrates that information sharing is facilitated by familiarity, and having a common understanding of problems, use of lexicon, and semantic meaning. Information-seeking behavior of design, process, and manufacturing engineers. This said, researchers attempt to follow the process and use it to present their research findings in research reports and journal articles. Q1: What is the meaning of Reliability and validity in research context? The first kind is the alternate-form reliability.
This serves as the focus of the study. Thirdly, errors and non-responsive attitude of the participants might cause problems in the sample representation.

In other words validity means the results of a research instrument relates to our criteria. For the purpose of this research, the researcher will focus on case study strategy. Additional background information may be found in your lecture notes, textbooks, and reserve readings.
