Alan Bryman Social Research Methods Chapter 27: Mixed methods research: combining quantitative and qualitative research Slides authored by Tom Owens
The embedded methods argument: research methods carry epistemological and ontological commitments thus multi-strategy research is not feasible or even desirable The paradigmargument: quantitative and qualitative research are separate, incommensurable paradigms thus even when combined they are incompatible The argument against multi-strategy research Pages 629,630
Epistemological version incompatible epistemological principles of quantitative and qualitative research e.g. embedded methods /paradigm arguments Technical version quantitative and qualitative research strategies can be combined relative strengths and weaknesses of each for data collection / analysis Two versions of the debate Page 631
Bryman’s classification of approaches to mixed methods research 1.Triangulation; 2.Offset; 3.Completeness; 4.Process; 5.Different research questions; 6.Explanation; 7.Unexpected results; 8.Instrument development; 9.Sampling; 10.Credibility; 11.Context; 12.Illustration; 13.Utility; 14.Confirm and discover; 15.Diversity of views; 16.Enhancement. Thinking deeply 27.3 Pages 633,634
Results of one method/research strategy can be cross-checked against the results of another e.g. Silva and Wright (2008): Cultural Capital and Social Exclusion qualitative interviews conducted to ‘check and correct’ the quantitative data Planned or unplanned What happens if results are inconsistent? treat one set of results as definitive but better to re-examine the data Triangulation Pages 635,636
When neither research strategy can provide all the answers e.g. particular methods do not provide access to required information / groups of people Quantitative and qualitative methods both compensate for the other’s weaknesses e.g. when ethnographers use structured interviewing or self-completion questionnaires, because not everything of research interest is accessible through observation. Offset and Completeness Pages 636
Quantitative research can uncover regularities Qualitative research reveals social processes e.g. Holdsworth (2006) used a web-based questionnaire survey to provide a broad picture of differences between university students living at home and living away from home and qualitativeinterviews and focus groups to explore the processes that lie behind those differences. Process Pages 639,640
Quantitative research is better suited to the study of ‘macro’ phenomena (such as social mobility) Qualitative research is better suited to the study of ‘micro’ phenomena (such as small group interaction) Different phases in a research study suit one strategy more than another, because of the different aspects studied Different kinds of research questions are better answered by one strategy more than another Leading to choices of methods – and how they should be interweaved - in mixed methods research Different research questions Pages 640
Explanation Quantitative researchers constantly face the problem of explaining the relationships between variables. Qualitative research can discover the presence and role of intervening variables. Pages 641, 642
Research outcomes can yield unexpected results, inconsistent data and puzzling surprises. Sometimes anticipated results fail to materialize, such that findings are inconsistent with the research hypothesis, So using a second method can help to explain data (unplanned triangulation), Or can provide a ‘salvage operation’ as an alternative to reconstructing the hypothesis or simply filing them away. Unexpected results Pages 642
By aiding measurement: focus groups and semi-structured interviews can provide the measurements of concepts to be tested in quantitative research, leading to much more appropriate specification of questions. Instrument development Pages 642-644
Sampling By providing a basis for representative sampling in qualitative research: samples of people or companies, with particular sets of characteristics, for in- depth interviewing or case study. Pages 644,645
Credibility • Some quantification of findings from qualitative research can help to make the study seem more believable • Mixed methods research is often done because of its appeal to funders and sponsors Page 645
Diversity of views • Quantitative methods test researcher’s theories; • Qualitative methods make participants’ meanings the center of attention; • Some research studies require both perspectives. Pages 647,648
Morgan’s (1998) classification The priority decision: How far is a qualitative or a quantitative method the principal data-gathering tool or do they have equal weight? The sequence decision: Which method precedes which? In other words, does the qualitative method precede the quantitative one or vice versa or is the data collection associated with each method concurrent? Thinking deeply 27.2 Page 631
Morgan’s types of mixed methods in terms of priority and sequence Figure 27.1 Page 632
Increasingly common in social research research methods seen as autonomous softening of feminist attitudes to quantification Not inherently superior to mono-method or mono-strategy research Reflections on mixed methods research Pages 649,650
Indicators of quality in mixed methods research • Is it well designed and conducted? • Are the methods appropriate to the research questions? • Is there an explicit rationale for the mixture? • Are the separate components integrated? • Is there a detailed account of the entire research process? • Are resources spread too thinly, or unevenly? • Are the researchers more skilled in one strategy than another?
