reliability validity and trustworthiness in quantitative research

This improves the credibility of a study because it shows that the researchers are looking over the cases thoroughly, and it allows researchers to present information from a study that does not align with other themes, patterns, and overall results.Ħ.

Negative case analysis is used to show that not all the data will provide the same result. 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.ĥ. Peer debriefing is used to help make sure none of the researchers are using their biased opinion.

Contextual validation plays a role in triangulation because it examines the validity of a piece of a study by comparing it with other kinds of evidence on same points to find a similar characteristic style or distortion in a source.Ĥ. Multiple theories are examined because theories can be interrelated, and findings could result in a function of the similarity of theories. Several different investigators are used to examine if one researcher is more or less honest from other team members. Triangulation is an activity used to examine a substantial amount of various sources (i.e., interviewing and observation), methods, investigators, and theories. Persistent observation is used to examine credibility by looking in-depth at what the researchers are examining and investigating factor in detail.ģ. It is crucial for researchers to spend a good amount of time at a site and examine any distortions, including perceptual, selective, and misconstruction of investigator’s questions.Ģ. Prolonged engagement is an activity qualitative researchers use to learn traditions and customs of the participants and build trust. The following are procedures qualitative researchers can use to increase credibility in qualitative studies:ġ. For qualitative researchers, credibility is a method that includes researchers taking on activities that increase probability so that there will be trustworthy findings.

For quantitative researchers, the methods used to establish trustworthiness include internal validity, external validity, reliability, and objectivity.Ĭredibility 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. For qualitative researchers, the methods used to establish trustworthiness include credibility, transferability, dependability, and confirmability. The methods used by quantitative and qualitative researchers to establish trustworthiness differ in many ways.
