The Examination Of Nonparametric Person-Fit Statistics As Appropriate Measures Of Response Bias In Ordered Polytomous Items, Mark F. Beck
The Examination Of Nonparametric Person-Fit Statistics As Appropriate Measures Of Response Bias In Ordered Polytomous Items, Mark F. Beck
College of Education and Human Sciences: Dissertations, Theses, and Student Research
Survey research is ubiquitous within the social sciences; however, surveys are vulnerable to response biases. Response biases introduce construct-irrelevant variance into survey responses, which degrades the accuracy of conclusions drawn through the use of surveys. Nonparametric person-fit statistics have been shown to accurately identify response biases in dichotomous response data but are not well studied in polytomous response data. This study examines the accuracy of nonparametric person-fit statistics in polytomous response data. A 6 x 4 x 4 x 2 simulation study was conducted, with type of aberrancy (6), number of response options (4), dimensionality (4), and test length (2) …
Assessing Quality In Mixed Methods Research: A Case Study Operationalizing The Legitimation Typology, Analay Perez
Assessing Quality In Mixed Methods Research: A Case Study Operationalizing The Legitimation Typology, Analay Perez
College of Education and Human Sciences: Dissertations, Theses, and Student Research
Quality in mixed methods research (MMR) has been an ongoing topic of discussion over the past two decades. One of the obstacles of assessing quality in a MMR study is developing credible inferences from the integration of quantitative and qualitative approaches (Plano Clark & Ivankova, 2016). Some researchers have designed a variety of strategies for assessing quality of a mixed methods study as a whole (Teddlie, & Tashakkori, 2003; Onwuegbuzie & Johnson, 2006; Tashakkori, & Teddlie, 2003), but there is no general consensus among researchers on which methods to use. The aim of this intrinsic, exploratory case study was to …
Guidelines For Interpretive Interview Fidelity In Mixed Methods Research Within The Context Of A Randomized Controlled Trial, Amanda L. Garrett
Guidelines For Interpretive Interview Fidelity In Mixed Methods Research Within The Context Of A Randomized Controlled Trial, Amanda L. Garrett
College of Education and Human Sciences: Dissertations, Theses, and Student Research
Interviews fascinate and capture individuals’ attention. Researchers value the data they glean from interviews, while participants enjoy being asked to share their voices and opinions. Some of the most complex, stringent research designs are now being revised to include interviews, such as randomized controlled trials. But, how do we know that the interviews that are conducted are valid? We need to know more about how interviews are developed and delivered within the context of intervention research. Therefore, the aim of this methodological dissertation is to create a set of recommendations for interpretive interviews in a mixed methods randomized controlled trial. …
