Analyzing Qualitative Data
A process of making sense of non-numeric data. Data from: Narrative documents (speeches, newspapers, diaries, reports, etc) Open-ended interviews Open-ended questions on a survey Case study (as the principal method or as embedded in a larger
complex of qualitative data and forms of analysis). Often, qualitative evaluation research incorporates cross-case
analysis: For instance in evaluating two sites of the same program, or in assessing a program site against another without the intervention. An example might be a school with an extended learning program to others without it.

Qualitative Data AnalysisData From Focus groups transcripts; interview transcripts and notes Unstructured observations Document review Videos, etc.
The goal is to identify common themes Requires a solid plan, attention to detail, good organization and
sufficient time Whether the analysis is done by computer or by hand, it is often
necessary to develop a coding scheme so the data can be systematically organized and analyzed
Computer software can help locate and organize data according to the coding scheme created
Dr. G. Johnson, Dr. M. Rivera 4
Qualitative Data Analysis But the analysis—that is, making sense of the data, discovering
the story the data reveals—is done by the researcher(s) The greatest concern is bias/paradigm blinders: hard to
recognize things you do not expect, or to avoid finding things you are inclined to find.
Maintaining the Thread Review the data, make notes as you go along Read again once all the data collection is completed
Organize the data—according to research questions, by date, by geographic location—what makes sense given the situation
Begin to look for recurrent themes. In one cross-case evaluation of a family-based drug education program, for instance, the instructor (Rivera) found clear commonalities and divergences in program-development in two Navajo communities in New Mexico.
Dr. G. Johnson, Dr. M. Rivera 5
Basic Activities: Preliminary Analysis Identify common words, ideas, themes Develop spreadsheet or write on index cards Identify “quotable quotes”—that is, quotes that highlight
the key issues: general views, divergent views, a range views. In evaluating an afterschool science program for middle-school students, Dr. Rivera conducted short interviews with students and with their parents, on various occasions. These exchanges produced quotes pertaining to favorite and least favorite parts of the program, parents’ views on program impact on students, etc. In another program evaluation, short quotations from participants supplemented survey results.
Dr. G. Johnson, Dr. M. Rivera 6
Qualitative Data Analysis: Coding Process When applicable (focus groups, content analysis of documents),
code the data Identify common word, issues, themes and go through the
material and label them according to that coding scheme You may go through the material several times Sometimes a major theme emerges at the end and you will need
to go back through to see if it was present in the earlier data Software is available that may help. Major software are
ATLAS.ti and NUD*IST, others like NVivo are specialized for various uses. There is growing literature on the use of computer- assisted qualitative data analysis software (CAQDAS).
Researchers might also use spreadsheets, index cards, color coding of documents, or other devices or combinations of these.

Ensuring Quality in Qualitative Analysis
Work to ensure inter-rater reliability Like content analysis, the researchers should review the same
material and apply the coding scheme Then review and determine if there are difference Discuss, revise the coding scheme if necessary and retrain the
coders Repeat this test until there is agreement in the coding
Compare results, work out differences, then code all the material Inter-rater reliability was a major concern in the assessment of
teacher dossiers for advancement in tier, in Dr. Rivera’s evaluation of Three-tier Teacher Licensure in New Mexico in 2003-2004. Several trial (but real) assessments of dossiers by 3-person rater teams, of teacher volunteering to be thus evaluated, were tried during 2004-05, a transitional year for the new system.
Qualitative Data Analysis: General Process Interpreting the data
Making sense of the data: Review salient themes Are there any seeming relationships between the themes or
characteristics? What are the major points that emerge from the analysis?
What about minor points? Sometimes an uncommon theme stands out, or is noted by one or two
investigators The researchers need to consider that perspective; always indicate
when it is a minority view and be careful that it does not trump majority views
When evaluating programs, principal investigators and program managers are often engaged in conjoint analysis by or with the evaluator. Eliciting a variety of views is important.
These are stakeholders, and stakeholders, when really engaged, make us smarter. Cf. Chen on “stakeholder validity” vs. scientific validity.*
*Chen, H. (2005). Practical program evaluation: Assessing and improving planning, implementation, and effectiveness. Thousand Oaks: Sage Publications.
One stakeholder engagement technique: the Affinity Diagram A group process for analyzing qualitative data:
Research team reviews the material In silence, write down each idea, key work theme on a sticky
note In silence, post on wall In silence, sort into similar categories Once the notes are organized, discuss; look for consensus
themes Interpret the data with stakeholders
Reality check: do others involved in program or project agree? Share preliminary drafts with stakeholders or a small group of
the participants to explore the issues you have discovered Share final draft with experts and cold readers
Affinity Diagram Identify common themes The Affinity Diagram tool is a quick way to set up a coding
framework It is also a great way to identify the major themes and topics in
the final article or report It has the advantage of capturing all ideas in a room Everyone’s ideas have equal value when posted
Focus on major themes: “Some said X, while others said Y . . .” Avoid generalizations: if not everyone was asked to comment
about a particular practice, you do not know if the five who commented represented the views of others or were just the only ones that thought this practice was important.
Dr. G. Johnson, Dr. Mario Rivera 11
Leading Discussion and Writing Up Results—Could function as a facilitated focus group
Provide a range of perspectives. Highlight interesting perspectives even if only said by one
or two people. A few offered unique views: “….” These might be important because “…..”
Do not try to report numbers or percents unless everyone was counted in exactly the same way For example, 10 people out of the 20 who you interviewed
commented that they liked the training program. But unless you asked all 20 people, you do not know what the
other 10 people thought.
Limitations of Qualitative Data Analysis It can be like a Rorschach test –an inkblot that some see as a
butterfly and others see as maple leaf Reasonable people can read the same material and have very
different interpretations. It is important to explore those differences to gain a deeper understanding rather than to win the argument
It is much more difficult to generalize from qualitative analysis than otherwise. Questions of validity, reliability, replicability, etc., inevitably arise with qualitative data. These may be overweighed by the richness of insight gleaned from the data (“thick description”), but these challenges need to be taken into account and addressed with some directness in research reports.
Best when combined with quantitative analysis in mixed-methods research, which allows for triangulation of data and methods alike.
