Week 11
Veal Chapter 15, CDS Chapter 07
2. Objectives Describe the overlap between data gathering and data analysis in qualitative research
Explain the difference between the analysis of data gathered by structured methods and that gathered by unstructured methods
Describe the process of content analysis
Describe how a computer package can assist the researcher in analysing qualitative data
3. Overlap Collection and analysis occur simultaneously
Human-as-an-instrument
Strength:
The researcher can use the results to probe for further information and detail
and Weakness:
Can divert attention away from research objectives
4. Aims of qualitative analysis Understand the phenomenon
Go beyond reporting – move towards INTERPRETATION
Identify themes and sub-themes
5. Data storage and confidentiality Because qualitative data may include personal opinions and details:
Security of data storage is important
Ideally, pseudonyms/codes should be used even with stored data/transcripts etc.
Efforts should be made to protect confidentiality/ anonymity of informants when reporting results
6. Structured methods Use pre-planned questions from structured interview or focus group
Identify common responses within each question
May still have some variety that will need content analysis (unstructured method)
7. Quantifying methods Informal methods: identify repetitive or patterned behaviour
Frequencies
Content analysis: converting text to numerical variables.
Use coding units - words, themes, items, time
Repertory grid: mental maps
8. Example - Frequencies
9. Content analysis The process of identifying, coding and categorising the primary patterns in the data
Constant comparative analysis
reads raw data and identifies an important point
Continues reading and identifies another point
Compares to first point and so on
10. Content analysis process (1) Prepare and organise raw data
Source code all raw data
Copy raw data
Store originals of raw data in safe place
Read
Theme coding system
Compare first theme with second theme and so on
11. Content analysis process (2) Data index and classification (coding frame)
Transfer indicated passages to a file
Open coding
Axial coding
Rules for inclusion
Selective coding
Mapping
Write report
12. Preparation stages Prepare and organise raw data – transcribe information and audio material
Source code all raw data – identify where the information was originally obtained
Example - IA3b4: Interview, with Administrator 3, in the second interview, from page 4 of the transcript
Copy raw textual data - tends to get marked and destroyed
Store originals of raw data in safe place – filing cabinet, locker – secure location required
Read through notes – first take, to get overall picture of what you have seen.
13. Reading + Emergent themes Reading
The key activity in qualitative data analysis is reading and re-reading the material
Reading begins with initial research questions/models etc. in mind – but evolves
Emergent themes
Ideas/concepts which emerge are referred to as ‘emergent themes’
For one scenario, see:
Fig. 15.2 – Initial outline conceptual framework
Fig. 15.3 – Annotated interview transcripts
Fig. 15.4 – Further developed conceptual framework
14. Outline/Initial/Simple conceptual framework
15. Interview transcript extract – annotated – Fig. 15.3 (p. 296)
16. Partially developed conceptual framework – Fig. 15.4
17. Mechanics Annotate transcripts with ‘themes’ – as in Fig. 15.3
Need to leave wide margins or use ‘columns’
Colour coding may be helpful
Word-processor may be used to:
Add comments/block text in colour, underline or bold
Search for words/phrases
Code and cross-reference using indexing
Numbering paragraphs may be useful for cataloguing
Eg. Career attitude-strategic - Mark: p. 2, para. 3; p. 7, para 4; Jennie: p. 7, para. 1
18. 6 – 9 Open coding First pass through data
Study field notes.
Locate themes, assign initial codes or labels (step 6)
Themes comes from initial question, literature, or from the data.
Similar to a filing system
Aim is to reduce data to manageable categories
19. Axial coding Second pass through data.
Focus on initial coded themes.
Determine consequences, conditions, interactions, processes….
Seek to identify causal patterns in the data
20. Six Ways to Discover Patterns Frequencies
Magnitudes
Structures
Processes
Causes
Consequences
21. Rules for inclusion Properties or characteristics of passages in the data that identify it as relevant to that category
i.e. What is included, what is excluded:
May occur at open or axial coding stage
22. Selective coding Third/last pass through data.
Involves scanning data and previous codes.
Look for evidence to support themes developed
E.g. text samples
Identify major themes of research, and contrast between themes.
Can involve collapsing themes together (e.g. is there a need for separate categories of seating)
23. Unstructured procedure Convert field notes into written record (reference field notes)
Code data to allow storage and retrieval
Write summaries at various stages
Use summaries to construct generalisations to confront existing theories or construct new theories
24. Mind mapping “Mind maps were developed in the late 60s by Tony Buzan as a way of helping students make notes that used only key words and images. They are much quicker to make, and because of their visual quality much easier to remember and review. The non-linear nature of mind maps makes it easy to link and cross-reference different elements of the map.”

26. How to mind map (Russell, 1997) Use just key words, or wherever possible images.
Start from the center of the page and work out.
Make the center a clear and strong visual image that depicts the general theme of the map.
Create sub-centers for sub-themes.
Put key words on lines. This reinforces structure of notes.
Print rather than write in script. It makes them more readable and memorable. Lower case is more visually distinctive (and better remembered) than upper case.
Use color to depict themes, associations and to make things stand out. Anything that stands out on the page will stand out in your mind.
Think three-dimensionally.
Use arrows, icons or other visual aids to show links between different elements.
Don't get stuck in one area. If you dry up in one area go to another branch.
Put ideas down as they occur, wherever they fit. Don't judge or hold back.
Break boundaries. If you run out of space, don't start a new sheet; paste more paper onto the map. (Break the 8x11 mentality.)
Be creative. Creativity aids memory.
Get involved. Have fun.
27. Displaying qualitative data Often qualitative data can be best represented through visual methods
Matrices: e.g. events flow matrix, effects matrix
Charts and graphs
Mapping: generate conceptual frameworks from themes
28. Effects matrix
29. ‘Crosstabulation’ of qualitative data – Fig. 15.5
30. Mapping example – CDS Fig.7.8
31. Using a computer package Can only assist human judgement
E.g. Nvivo, NUD*IST
32. The qualitative analysis process Overlap between gathering and analysis
Manifest vs latent content
Decisions are yours
Gathering data, analysing data and writing report are not mutually exclusive
Need to recognise and account for the role of the researcher in the analysis
