Develop reliability and validity coefficients for appropriate data. Understanding the importance of collecting qualitative data creatively Abstract IN ITS broadest sense, qualitative research encompasses any study that does not use statistical methods or quantify results (Strauss and Corbin 1990). However, even for school leaders who may not have the resources to perform proper statistical analysis, an understanding of these concepts will still 3. research bias is important for several reasons: first, bias exists in all research, across research designs and is difficult to eliminate; second, bias can occur at each stage of the research process; third, bias impacts on the validity and reliability of study findings and Reliability refers to the ability to consistently produce a given result. Establishing validity and reliability in qualitative research can be less precise, though participant/member checks, peer evaluation (another researcher checks the researcher’s inferences based on the instrument (Denzin & Lincoln Vol.IV No.1 2008 pp35-45 39 Reliability and Validity in Qualitative Research To understand the meaning of reliability and validity… Home » Online Research » Triangulation and its importance in research Triangulation is the process of validating the results of a study through two or more methods to check its reliability and validity.
