  1. Qualitative analysiscoding (intro exercises)affinity diagramsCSCI 4163/6610 - winter 2015

  2. Agenda • 2 Main QA approaches • Coding exercise 1 • Coding exercise 2 • Slides on Qualitative Analysis • Brainstorming Exercise (if time) • Affinity Diagramming Exercise (if time)

  3. Qualitative Research: Common Features of Analytic Methods (Miles & Huberman,1994) • Affixing codes to a set of field notes drawn from data collection • Noting reflections or other remarks in margin • Sorting or shifting through the materials to identify similar phrases, relationships between themes, distinct differences between subgroups and common sequences

  4. Qualitative Research: Common Features of Analytic Methods (Miles & Huberman,1994) • Isolating patterns and processes, commonalties and differences, and taking them out to the field in the next wave of data collection • Gradually elaborating a small set of generalisations that cover the consistencies discerned in the data base • Confronting those generalisations with a formalised body of knowledge in the form of constructs or theories

  5. 2 general research approaches deductive approach vs inductive approach

  6. deductive research approach THEORY Top-down approach Theory testing A priori codes HYPOTHESIS OBSERVATION CONFIRMATION

  7. inductive research approach THEORY TENTATIVE HYPOTHESIS PATTERN bottom-up approach Theory building Emergent codes OBSERVATION

  8. deductive or inductive

  9. Often use a hybrid approach • A set of a priori codes reflecting your understanding of the topic and your research questions • Emergent codes added as you code the data and find other factors/topics/codes that you had not considered

  10. Exercise 1 • Open coding • Inductive analysis • Exploratory research • Theory building research • http://b.socrative.com/login/student/ • Room: 7f156b7b

  11. Exercise 2 • Coding with pre-defined categories • Deductive analysis • Theory Testing • http://b.socrative.com/login/student/ • Room: 7f156b7b

  12. The Qualitative Analytical Process

  13. Qualitative Inquiry - Purpose The purpose of qualitative inquiry is to produce findings. The Data Collection process is not an end in itself. The culminating activities of qualitative inquiry are analysis, interpretation, and presentation of findings.

  14. Qualitative Inquiry - Challenge • To make sense of massive amounts of data, reduce the volume of information, identify significant patterns and construct a framework for communicating the essence of what the data reveal

  15. Qualitative Inquiry - Problem • ‘…have few agreed-on canons for qualitative data analysis, in the sense of shared ground rules for drawing conclusions and verifying sturdiness’ (Miles and Huberman, 1984)

  16. The Creativity of Qualitative Inquiry • ‘..the human element of qualitative inquiry is both its strength and weakness - its strength is fully using human insight and experience, its weakness is being so heavily dependent on the researcher’s skill, training, intellect, discipline, and creativity. The researcher is the instrument of qualitative inquiry, so the quality of the research depends heavily on the qualities of that human being’ (Patton, 1988)

  17. The Science and Art of Qualitative Inquiry (Patton, 1988) • The Science • The scientific part is systematic, analytical, rigorous, disciplined, and critical in perspective • The Art • The artistic part is exploring, playful, metaphorical, insightful, and creative

  18. 1. Analysis Considerations • Words • Context (tone and inflection) • Internal consistency (opinion shifts during groups) • Frequency and intensity of comments (counting, content analysis) • Specificity • Trends/themes • Iteration (data collection and analysis is an iterative process moving back and forth)

  19. 2. The Procedures • Coding/indexing • Categorisation • Abstraction • Comparison • Dimensionalisation (relationships) • Integration • Iteration • Refutation (subjecting inferences to scrutiny) • Interpretation (grasp of meaning - difficult to describe procedurally)

  20. Critical Thinking • ‘Critical Thinking calls for a persistent effort to examine any belief or supposed form of knowledge in the light of the evidence that supports it and the further conclusions to which it tends’ (Glaser, 1941) • or more simply! • Critical Thinking means weighting up the arguments and evidence for and against.

  21. Critical Thinking • Key points (Glaser, 1941): • Persistence: Considering an issue carefully and more than once • Evidence: Evaluating the evidence put forward in support of the belief or viewpoint • Implications: Considering where the belief or viewpoint leads; what conclusions would follow; are these suitable and rational; and if not, should the belief or viewpoint be reconsidered

  22. Guidance for Creative Thinking • Be open • Generate options • Divergence before convergence • Use multiple stimuli - triangulate • Side track, zig-zag, and circumnavigate • Change patterns of thinking • Make linkages • Trust yourself • Work and play at it

  23. The Credibility of Qualitative Analysis • Rigorous techniques and methods for gathering high-quality data that is carefully analysed, with attention to issues of validity, reliability, and triangulation • The credibility of the researcher, which is dependent on training, experience, track record, status, and presentation of self • Philosophical belief in the phenomenological paradigm, that is, a fundamental appreciation of naturalistic inquiry, qualitative methods, inductive analysis and holistic thinking

  24. A Credible Qualitative Study A credible qualitative study needs to address the following issues: • What techniques and methods were used to ensure the integrity, validity, and accuracy of the findings • What does the researcher bring to study in terms of qualifications, experience, and perspective • What paradigm orientation and assumptions ground the study

  25. Principles of Analysing Qualitative Data • Proceed systematically and rigorously (minimise human error) • Record process, memos, journals, etc. • Focus on responding to research questions • Appropriate level of interpretation appropriate for situation • Time (process of inquiry and analysis are often simultaneous) • Seek to explain or enlighten • Evolutionary/emerging

  26. Inter-rater reliability • What if you have more than one person coding? • How much agreement do they have? • At what point should you test their agreement? • Other than comparing counts, how can you validate the coding/analysis? • https://www.academia.edu/458025/The_place_of_inter-rater_reliability_in_qualitative_research_an_empirical_study

  27. Interface Design and Usability Engineering • Articulate: • who users are • their key tasks Brainstorm designs Refined designs Completed designs Goals: Task centered system design Participatory design User-centered design Graphical screen design Interface guidelines Style guides Psychology of everyday things User involvement Representation & metaphors Participatory interaction Task / Cognitive scenario walk-through Evaluate Usability testing Heuristic evaluation Field testing Methods: high fidelity prototyping methods low fidelity prototyping methods Or to pre-existing designs back here Throw-away paper prototypes Products: User and task descriptions Testable prototypes Alpha/beta systems or complete specification

  28. brainstorming • the point is: • to generate MANY, WIDE-RANGING ideas  nutty and absurd are GOOD. go for the extremes (to get out of the rut)  riff off other’s ideas. • the point is NOT: • to generate excellent, complete, feasible ideas… pressure stifles • to develop or critique ideas… go wide. deep is for later.

  29. process • prepare a list of topics / questionsahead of time; or in a preliminary brainstorm • facilitator takes team through list of topics switch topic when energy ramps down • Note takertakes notes (very important) • switch roles so everyone can play • ground rules • Follow up

  30. brainstorming is like popcorn

  31. ground rules • Postpone and withhold your judgment of ideas: never criticize • Encourage wild and exaggerated ideas • Quantity counts at this stage, not quality • Switch topics when the popcorn slows down • Build on the ideas put forward by others • Every person and every idea has equal worth • Elect a facilitator (calls switches) and a note-taker (one thought per post it!)

  32. Post brain-storm • collect the notes • go through carefully, with judgment turned on • look for • interesting, surprising ideas that might work • ideas that will combine well • promising directions on which you should brainstorm more • keep your notes. at a later design stage, come back to them and see if anything else has become useful in the meantime.

  33. Sometimes you have a lot of ideas to make sense of!

  34. work consolidation:abstracting specific insights • one tool: the affinity diagram • can use to “consolidate” insights from collected or generated data. for example: • brainstorming about design problems  categories of problems • brainstorming about design ideas categories of ideas • comments from users  categories of desirable / successful features

  35. how do you make an affinity diagram? • team writes down all data & insights on post-it notes; be sure you can link the post-it detail back to its source! • stick one post-it on the wall a whiteboard or big sheet of butcher paper is best • arrange the other post-its around it, grouping by affinity to each other. iteration will be required. • look at each group and see what it has in common; name and describe each group. • “snapshot” the result for documentation • digital photo  your design website or notebook • transfer post-its onto paper, 1 sheet / notes-cluster  scan  website

  36. why does an affinity diagram work? • use physical arrangement/proximity to understand connections • openness to serendipity • low cost to rearrange ideas • many variants: • arrange along axes rather than by affinity • tie causes to effects • group evidence under assertions
