Quality criteria in quantitative research

Through critical appraisal of the reasons for designing mixed-methods research, three criteria resulted validation, complementarity, and discrepancy. In applying the criteria to empirical data of a previous mixed methods study, integration of quantitative and qualitative data was achieved in a systematic manner.. Web. Abstract In this article criteria for quality in qualitative research will be described, discussed, and compared with the usual criteria for quantitative research. This paper will focus on Lincoln & Guba&39;s concept of trustworthiness (1985). We hope to support novice qualitative researchers and to stimulate further discussion. Publication types. For instance, Guba and Lincoln proposed four criteria for judging the soundness of qualitative research and explicitly offered these as an alternative to more traditional quantitatively-oriented criteria. They felt that their four criteria better reflected the underlying assumptions involved in much qualitative research. The purpose of this article is to provide researchers with a framework for promoting high quality mixed methods school-based consultation research. Furthermore, this article is intended for researchers and practitioners interested in evaluating their practice. To meet these objectives, we address quality criteria for quantitative (validity) and qualitative (trustworthiness). Section three argues that quantitativepositivistic ideals have been inherent in logistics, thus favoring quality criteria such as objectivity, validity and reliability. On the other hand, indications of qualitative approaches gaining ground in logistics research call for a corresponding discussion on the role of alternative criteria. Web. Background When Candida species is found in a sputum culture, clinicians generally dismiss it as a contaminant. We sought to identify cases of community-acquired pneumonia (CAP) in which Candida might play a contributory etiologic role. Methods In a convenience sample of patients hospitalized for CAP, we screened for "high-quality sputum" by Gram stain (> 20 WBCepithelial cell) and. It then argues that qualitative research can be assessed with reference to the same broad criteria of quality as quantitative research, albeit the meaning attributed to these criteria may not be exactly the same and they may be assessed differently. The chapter concludes with a list of questions that can be used as a guide to assessing the. Web. Web. Web. Web.
