Data Analysis Analyzing Qualitative Data: A Technical Note For Lead Impact Assessment Researchers OVERVIEW This technical note is aimed at lead researchers and their teams. The purpose of the note is to serve as a reminder or refresher regarding some basics of good qualitative data analysis. The note is neither toolbox, nor comprehensive introduction to data analysis, nor training mechanism for novice researchers. DEFINING ‘ANALYSIS’ More than likely, we all actually have different mental models of what “analysis” is and, therefore, how it should be done. Two definitions are complementary and helpful. The first is very general, applying to just about any thought process: Analysis is the search for patterns in data and for ideas that help explain why those patterns are there in the first place (Bernard 2002, 429). The second ties this generic definition more tightly to research: Data analysis consists of examining, categorizing, tabulating, testing, or otherwise recombining…evidence to address the initial propositions of a study (Yin 2003, 109). So, data analysis is about the identification of patterns, patterns that connect to the questions being studied. ANALYTIC STRATEGIES The goal of an analytic strategy is “to treat the evidence fairly, produce compelling analytic conclusions, and rule out alternative interpretations” (Yin 2003, 111). Much impact assessment qualitative research will require “analytical induction.” This is a very fancy phrase. Simply put, analytical induction is a formal, qualitative method for building up causal explanations of phenomena from a close examination of cases (Bernard 2002, 512). Generic Analytical Strategies There are three generic analytical strategies for you to chose. They are: Test a Theory Investigate rival explanations Develop your own theory or causal model The table below summarizes them. Approaches Within any particular analytical strategy, there are three approaches that help you identify and make sense of patterns in the data Causal Webs Time-Series Analysis Logic Models They are summarized in the table below. Analytic Strategies and General Approaches (adapted from Yin (2003, Chapter 5) Strategy Test a theory Investigate rival explanations Develop your own theory or causal model Strategic Intent Follow your theory/hypotheses and use techniques that permit you to investigate the causal relationships you have proposed. Ideally, your study design has been linked to a wider theory base, to existing questions in the literature, and so forth. Establish rival explanations and interrogate your data with them. This strategy can be combined with the first. “Rival explanations” can include ones embedded in the research process itself (validity threats, researcher bias) but can also look explicitly at the possibility that other interventions can account for results observed (direct rival), that the researched intervention works in tandem with other variables (commingled rival), an alternative theory can account for the same observations (rival theory), or that other contextual factors produce the outcomes observed (social trends, for example). Particularly when conducting open-ended, exploratory research, a guiding analytic strategy can be to actually let the empirical data speak to you with the goal of developing a theory or model that explains observations. This is particularly common in studies that rely on grounded theory techniques (Strauss & Corbin 1998) Common Approaches All three of the approaches below are forms of “pattern matching” or comparing an empirically observed pattern against some predicted or expected one. All require looking at internal threats to validity; all require the identification, first, of patterns in the data…for which task you have scores of options of specific techniques. Causal Webs Time-Series Analysis Logic Models Specify a linked web of multiple dependent Analyzing the change over time between causes Deliberately simulates a complex series of variables that all should go together due to an and effects against a theoretically derived relationships over time. In essence, logic models intervention or interventions. Rigor and historical relationship specified prior to the onset combine causal webs and time-series analysis. persuasiveness is increased if your theory would of the study. This goes far beyond simple Frequently, logic models get produced in a predict different outcomes in different contexts, you chronologies of events as the focus is deeply iterative model between data gathering, investigate those contexts, and you find this indeed demonstrating or refuting a hypothesized set of analysis, returning to theory and hypotheses, to be the case. relationships back to data gathering for testing, etc. SPECIFIC TECHNIQUES Data analysis is intended to be a participative process involving CARE staff, researchers, and to the best of our ability women and men in the communities in which we are working and doing impact assessment. We need, therefore, to pay attention to the analysis techniques we use in terms of the skills, experience, and competencies that they require. We need to pay attention to both: a) Cross-cutting methodological principles and, b) Specific analytic techniques For more detail, see the full technical note. The note also contains guidance on achieving rigor in qualitative analysis through: 1. 2. 3. 4. Confirmability (objectivity); Dependability/Auditability (reliability); Credibility/Authenticity (internal validity); Transferability/Fittingness (external validity).
