2 general research approaches
deductive approach vs inductive approach
3
deductive research approach
THEORY top-down approach HYPOTHESIS Top-down approach, waterfall OBSERVATION CONFIRMATION
4
inductive research approach
THEORY TENTATIVE HYPOTHESIS Bottom up approach End goal is describe observations, formulate a theory.. PATTERN OBSERVATION bottom-up approach
5
deductive or inductive Deductive – theory testing
Inductive – theory building
6
Exercise 1 Open coding Inductive analysis Exploratory research
Theory building research
7
Exercise 2 Coding with pre-defined categories Deductive analysis
cpsc 344/544 - class 04a W1 Exercise 2 Coding with pre-defined categories Deductive analysis Theory Testing

Slides on Qualitative Analysis Brainstorming Exercise Affinity Diagramming Exercise
10
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)
11
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)
12
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.
13
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
14
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)
15
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)
16
The Science and Art of Qualitative Inquiry (Patton, 1988)
The scientific part is systematic, analytical, rigorous, disciplined, and critical in perspective The Art The artistic part is exploring, playful, metaphorical, insightful, and creative
17
cpsc 344/544 - class 04a W1 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.
18
Critical Thinking Key points (Glaser, 1941):
cpsc 344/544 - class 04a Critical Thinking W1 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
19
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 1. Creativity begins with openness to multiple possibilities 2. There is always more than one way to think about or do something 3. Begin by exploring a variety of directions and possibilities before focusing on the details. Branch out, go on mental excursions, and brainstorm multiple perspectives before converging on the most promising 4. Creativity training often includes exposure to many different avenues of expression: drawing, music, role-playing, constructing futuristic scenarios. Synthesising through triangulation is a creative use of multiple stimuli. 5. Creativity is seldom a result of purely linear and logical induction or deduction. The creative person explores back and forth, round and about, in and out, over and under. 6. Habits, standard, operating procedures, and patterned thinking are barriers to creativity. Become aware of and change your patterned ways of thinking and behaving 7. Many creative exercises include practice in learning how to connect the seemingly unconnected. 8. Self-doubt short circuits creative impulses. 9. Creativity is not all fun. It takes hard work, background research, and mental preparation 10. Creativity is not all work. It can be and should be play and fun.
20
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
21
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
22
Principles of Analysing Qualitative Data
cpsc 344/544 - class 04a W1 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 Evolution and emergence Interpretation and consequent understanding tends to evolve as the researcher explores, connects and re-reads data. Initial ideas are tentative and final theories emerge only after repeated and exhaustive exploration.
23
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
24
Qualitative Research: Common Features of Analytic Methods (Miles & Huberman,1994)
Isolating patterns and processes, commonalties and differences, and taking them out to the filed 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
25
Or to pre-existing designs back here
cpsc 344/544 - class 04a W1 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 Psychology of everyday things User involvement Representation & metaphors Graphical screen design Interface guidelines Style guides Participatory interaction Task / Cognitive scenario walk-through Evaluate Usability testing Heuristic evaluation Field testing Methods: low fidelity prototyping methods high fidelity prototyping methods Or to pre-existing designs back here Products: User and task descriptions Throw-away paper prototypes Testable prototypes Alpha/beta systems or complete specification
26
brainstorming the point is: the point is NOT:
cpsc 344/544 2010/11 Term 1 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.
27
cpsc 344/544 2010/11 Term 1 process prepare a list of topics / questions ahead of time; or in a preliminary brainstorm facilitator takes team through list of topics switch topic when energy ramps down Note taker takes notes (very important) switch roles so everyone can play ground rules Follow up
28
brainstorming is like popcorn
cpsc 344/544 2010/11 Term 1 brainstorming is like popcorn It is better to draw this on board or tablet, explaining as you go; scanned an image to make it clear to other presenters - draw a plot of idea frequency as a function of time (gaussian) - then draw another plot, with a series of guassians, each picking up where the previous one died down. “switch” points for facilitator - draw attention to this metaphor
29
cpsc 344/544 2010/11 Term 1 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!)
30
Form 5 groups assign a facilitator, note taker
cpsc 344/544 2010/11 Term 1 Form 5 groups assign a facilitator, note taker Problem: How to design the user interface for a car proximity detection system Brainstorm 3 aspects of the problem: (e.g., physical form factor, safety issues, input techniques, etc.) go: 5 minutes HIDE SLIDE IN POSTED VERSION
31
follow up collect the notes
cpsc 344/544 2010/11 Term 1 follow up 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.
32
work consolidation: abstracting specific insights
cpsc 344/544 2010/11 Term 1 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
33
how do you make an affinity diagram?
cpsc 344/544 2010/11 Term 1 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 xerox paper, 1 sheet / notes-cluster scan website
34
why does an affinity diagram work?
cpsc 344/544 2010/11 Term 1 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
36
affinity diagram exercise
cpsc 344/544 2010/11 Term 1 affinity diagram exercise Now take your notes from the earlier brainstorming and create an affinity diagram go: 8 minutes Start at 10:40
