Transferability - Results can be generalized to other settings.ĭependability - Opposed to the concept of reliability, research “describ the changes that occur in the setting and how these changes affected the way the research approached the study”Ĭonfirmability - Assumes that the researcher brings a unique perspective These are:Ĭredibility - Results are credible, or believable
Consequently, it doesn’t make sense to be concerned with the “truth” or “falsity” of an observation with respect to an external reality (which is a primary concern of validity).Īlternatively, Guba and Lincoln offered four criteria for researchers to simulate the objectives of validity and reliability for qualitative research. They reject the basic realist assumption that their is a reality external to our perception of it. According to Trochim:ĭepending on their philosophical perspectives, some qualitative researchers reject the framework of validity that is commonly accepted in more quantitative research in the social sciences.
In other words, the extent to which a research instrument consistently has the same results if it is used in the same situation on repeated occasions.įor qualitative, the argument is that validity and reliability do not necessarily apply to one’s perception of reality. Reliability the accuracy of an instrument.
To gain insight explore the depth, richness, and complexity inherent in the phenomenon.Validity is defined as the extent to which a concept is accurately measured in a quantitative study. A method used to describe, test relationships, and examine cause and effect relationships. Comparison of qualitative & quantitative researchĪ systematic subjective approach used to describe life experiences and give them meaningĪ formal, objective, systematic process for obtaining information about the world.
