The Analysis and
Interpretation of
Qualitative Data

Assumptions about qualitative data analysis
• If you have a substantial amount of qualitative data you will use some kind of software package to deal with it (standard word-processing software may be adequate)
• Unless you already have experience yourself, you will be helped or advised by someone who does have experience in this type of analysis

Different approaches to qualitative analysis
1 Quasi-statistical approaches
2 Thematic coding approach
3 Grounded theory approach

Common features of qualitative data analysis
• giving labels (‘codes’) to chunks (words, phrases, paragraphs, or whatever
• adding comments, reflections, etc. (commonly referred to as ‘memos’)
• going through the materials trying to identify similar phrases, patterns, themes, relationships, sequences, differences between subgroups, etc.

Common features of qualitative data analysis - continued
• using these patterns, themes, etc. to help focus further data collection
• gradually elaborating a small set of generalizations that cover the consistencies you discern in the data, and
• linking these generalizations to a formalized body of knowledge in the form of constructs or theories
(based on Miles and Huberman, 1994, p. 9)

Advantages of specialist QDA packages
• They provide an organized single location storage system for all stored material
• They give quick and easy access to coded material without using ‘cut and paste’
• They can handle large amounts of data very quickly• They force detailed consideration of all the text on
a line-by-line basis• They help the development of consistent coding
schemes• They can analyse differences, similarities and
relationships between coded elements• Many have a range of ways of displaying results
8©2011 John Wiley & Sons Ltd.
Disadvantages of specialist QDA packages
• Proficiency in their use takes time and effort• There may be difficulties in changing, or
reluctance to change, categories of information once they have been established
• Particular programs tend to impose specific approaches to data analysis
• Tendency to think that simply because you have used specialist software you have carried out a worthwhile analysis

Ways of keeping track of information
These include the use of:
• Session summary sheets• Document sheets• Memoing• The interim summary

Phases of thematic coding analysis
1 Familiarizing yourself with your data2 Generating initial codes3 Identifying themes4 Constructing thematic networks5 Integration and interpretation.
11©2011 John Wiley & Sons Ltd.
Advantages of thematic coding analysis
1 Very flexible, can be used with virtually all types of qualitative data
2 A relatively easy and quick method to learn and use
3 Accessible to those with little experience of qualitative research
4 The results of the analysis can be communicated without major difficulties to practitioners, policy makers and an educated general public

Advantages of thematic coding analysis - continued
5 A useful method to employ when working within a participatory research paradigm
6 Provides a means of summarizing key features of large amounts of qualitative data, using a principled approach
7 Not tied to a particular level of interpretation and can be used in a wide variety of fields and disciplines
(based, in part, on Braun and Clarke, 2006, pp. 96–7)
13©2011 John Wiley & Sons Ltd.
Disadvantages of thematic coding analysis
1 The flexibility of the method means that the potential range of things that can be said about your data is broad, which can be inhibiting
2 It is frequently limited to description or exploration with little interpretation
3 It is not uncommon to find little information about details of the procedure
4 Compared to ‘branded’ forms of analysis such as grounded theory it is a generic approach which currently has less kudos as an analytic method
(based, in part, on Braun and Clarke, 2006, pp. 96–7)

Using tables for comparative analysis
• Time-ordered tables where the columns are arranged in time sequence - includes event listing
• Role-ordered tables where the rows represent data from sets of individuals occupying different roles
• Conceptually clustered tables where the columns are arranged to being together items ‘belonging together’ (e.g. relating to same theme)
• Effects tables displaying data on outcomes• Issues tables where the columns concern issues
and what happens in connection with them

Using networks to understand patterns and relationships
Types include:
• Context charts• Event flow networks• Activity records• Flow charts• Conceptually ordered tree diagrams• Cognitive maps • Causal networks

1 Find conceptual categories in the data - through open coding
2 Find relationships between these categories - through axial coding

Data analysis in multi-strategy designs
1 Data reduction. Involves summarizing both quantitative and qualitative data
2 Data display. Using tables, graphs, etc. with quantitative data and matrices, charts, networks, etc. with qualitative data
3 Data transformation. ‘Qualitizing’ quantitative data and/or ‘quantizing’ qualitative data
4 Data correlation. Correlating quantitative data with qualitized data

5 Data consolidation. Combining both data types to create new variables or data sets.
6 Data comparison. Comparing data from different data sources.
7 Data integration. Integrating all data into a coherent whole, or separate quantitative and qualitative coherent wholes
Based on Onwuegbuzie and Teddlie (2003, p. 375)

Strategies for integrating quantitative and qualitative data through analysis
• Using results from analysis of one form of data in approaching the analysis of another form of data
• Synthesis of data generated from a variety of sources, for further joint interpretation
• Comparison of coded or thematic qualitative data across groups defined by categorical or scaled variables
• Pattern analysis using matrices

Strategies for integrating quantitative and qualitative data through analysis
- continued
• Conversion of qualitative to quantitative coding to allow for statistical analysis.
• Conversion of quantitative data into narrative form• Inherently mixed data analysis, where a single
source gives rise to both qualitative and quantitative information
• Iterative analyses involving multiple, sequenced phases where the conduct of each phase arises out of or draws on the analysis of the preceding phase.
