Integrating Data Analysis in Mixed Methods Research

Bazeley, Patricia (2009)

Journal of Mixed Methods Research, 3(3), 203-207

Encourages a thinking about mixed methods work based on a qualitative-quantitative continuum. Focuses primarily on strategy for mixed methods data analysis at various stages of the process rather than just integration at the end. Discusses the use of computer solutions to assist in the process. Although the epistemological arguments of the "paradigm wars" sharpened our thinking about issues related to mixed methodology, their lingering legacy has been to slow the progress of integration methods.

Mixed Methods Analysis and Information Visualization: Graphical Display for Effective Communication of Research Results

Onwuegbuzie, Anthony J. & Dickinson, W. B. (2008)

The Qualitative Report, 13(2), 204-225

Introduces a range of graphical methods that can be used to present mixed methods research results. Presents a taxonomy for the presentation of results in general (quan or qual) and then strategy for integrating qual-quant results in same framework. Frist, we present a broad taxonomy of visual representation. Next, we use this taxonomy to provide and overview of visual techniques for quantitative data display and qualitative data display. Then, we propose what we call "crossover" visual extensions to summarize and integrate both qualitative and quantitative results within the same framework.

Using Consensus Analysis to Measure Cultural Diversity in Organizations and Social Movements

Caulkins, Douglas & Hyatt, Susan B. (1999)

Field Methods, 11(1): 55-26

Introduces consensus analysis as useful technique for analyzing structured interview data and producing results that: a) measure the degree of agreement amont informants, b) identify "culturally correct" information, and c) assign scores for each informant on how knowledgeable they are with respect to the "correct" response.

Logistic Regression

Garson, G. David (2008)

www2.chass.ncsu.edu/garson?PA765/logistic.htm

Overview and how-to guide for specifying and interpreting the results of logistic regression. Logistic regression can be used to predict a dependent variable on the basis of continuous and/or categorical independents and to determine the percent of variance in the dependent variable • explained by the independents; to rank the relative importance of independents; to assess interaction effects; and to understand the impact of covariate control variables. Logistic regression applies maximum likelihood estimation after transforming the dependent into a logit variable (the natural log of the odds of the dependent occurring or not). In this way, logistic regression estimates the probability of a certain event occurring. Note that logistic regression calculates changes in the log odds of the dependent, not changes in the dependent itself as OLS regression does.

The Meaning of Kappa: Probabilistic Concepts of Reliability and Validity Revisited

Guggenmoos-Holzmann, Irene (1996)

Journal of Clinical Epidemiology, 49(7): 775-782

A Framework—the “agreement concept”—is developed to study the use of Cohen's kappa as well as alternative measures of chance-corrected agreement in a unified manner for qualitative and mixed methods research. Focusing on intrarater consistency it is demonstrated that for 2 × 2 tables an adequate choice between different measures of chance-corrected agreement can be made only if the characteristics of the observational setting are taken into account. In particular, a naive use of Cohen's kappa may lead to strinkingly overoptimistic estimates of chance-corrected agreement. Such bias can be overcome by more elaborate study designs that allow for an unrestricted estimation of the probabilities at issue. When Cohen's kappa is appropriately applied as a measure of chance-corrected agreement, its values prove to be a linear—and not a parabolic—function of true prevalence. It is further shown how the validity of ratings is influenced by lack of consistency. Depending on the design of a validity study, this may lead, on purely formal grounds, to prevalence-dependent estimates of sensitivity and specificity. Proposed formulas for “chance-corrected” validity indexes fail to adjust for this phenomenon. It is common practice to assess consistency of diagnostic ratings in terms of 'agreement beyond chance'. To explore the interpretation of such a term we consider relevant statistical techniques such as Cohen's kappa and log-linear models for agreement on nominal ratings. We relate these approaches to a special latent class concept that decomposes observed ratings into a class of systematically consistent and a class of fortuitous ratings. This decomposition provides a common framework in which the specific premises of Cohen's kappa and of log-linear models can be identified and put into perspective. As a result it is shown that Cohen's kappa may be an inadequate and biased index of chance-corrected agreement in studies of intra-observer as well as inter-observer consistency. We suggest a more critical use and interpretation of measures gauging observer reliability by the amount of agreement beyond chance.

Impacts of Children with Troubles on Working Poor Families: Experimental and Mixed Methods Evidence

Bernheimer, L., Weisner, T.S., & Lowe, E. (2003)

Mental Retardation, 41(6): 403-419

Mixed-method and experimental data on working poor families and children with troubles participating in the New Hope anti-poverty experimental initiative in Milwaukee are described. Sixty percent of these families had at least one child who had significant problems (learning, school achievement and/or behavior, home behavior, retardation, other disabilities). Control group families with children who had troubles had more difficulties in sustaining their family routine than did New Hope experimental families.

Unpackaging Cultural Effects on Classroom Learning: Hawaiian Peer Assistance and Child-Generated Activity

Weisner, T. S., Gallimore, R., & Jordan, C. (1988)

Anthropology and Education Quarterly, 19: 327-353

Cultural analysis of differential minority achievement can create stereotypes and restrict expectations of child performance if group-level cultural generalizations are misapplied to individuals. Observational and interview studies of sibling caretaking and peer assistance in Native Hawaiian contexts illustrate the appropriate comparative analysis of natal and school activity settings. Results indicate Native Hawaiian sibling caretaking varies widely across households and individual child experience. Parents' beliefs about sibcare show a mix of shared acceptance and ambivalence. In natal settings, child-generated activities, carried on without adult intervention, produce most literacy-related behaviors (such as school-like tasks and increased language use). Among the classroom learning activities that are successful with Native Hawaiian children are child-generated interactions, in which children are able to use scripts similar to those observed in natal settings. Other features of natal activity settings (such as personnel, goals and motives, and everyday tasks) are discontinuous with those of the classroom centers. To reduce home/school discontinuities, these data suggest that classrooms need to be accommodated to selected features of natal culture activity settings, rather than be isomorphic in all aspects. Identification of which cultural features these are depends on “unpackaging” cultural effects on individuals by analysis of both natal and school activity settings.

Toward a Definition of Mixed Methods Research

Johnson, R. Burke, Onwuegbuzie, Anthony J., & Turner, Lisa A. (2007)

Journal of Mixed Methods Research, 1(2), 112-133

Examines the definition of the emerging mixed methods research field. Surveyed major authors in the mixed method literature with regard to definition for the field and key issues that need to be addressed as the field advances. Results show a consensus of mixed methods as an emerging ‘research paradigm’ and a breadth of opinion around definition for the field.

What Good is Polarizing Research into Qualitative and Quantitative?

Ercikan, Kadriye & Roth, Wolff-Michael (2006)

Educational Researcher, 352(5), 12-23

The authors argue against a polarization between qualitative and quantitative methods and the associated polarization between “subjective” and “objective” evidence. In doing so, they encourage an understanding of the meaninglessness of such a distinction and the value of taking a more integrated approach. Finally, they map a more “continuous” perspective to addressing the needs of a particular research question and the study design and methodological decisions that follow.
