Qualitative Analysis
Qualitative analysis is the analysis of qualitative data such as text data from interview
transcripts. Unlike quantitative analysis, which is statistics driven and largely independent of
the researcher, qualitative analysis is heavily dependent on the researcher’s analytic and
integrative skills and personal knowledge of the social context where the data is collected. The
emphasis in qualitative analysis is “sense making” or understanding a phenomenon, rather than
predicting or explaining. A creative and investigative mindset is needed for qualitative analysis,
based on an ethically enlightened and participant-in-context attitude, and a set of analytic
strategies. This chapter provides a brief overview of some of these qualitative analysis
strategies. Interested readers are referred to more authoritative and detailed references such
as Miles and Huberman’s (1984)17 seminal book on this topic.
Grounded Theory
How can you analyze a vast set qualitative data acquired through participant
observation, in-depth interviews, focus groups, narratives of audio/video recordings, or
secondary documents? One of these techniques for analyzing text data is grounded theory –
an inductive technique of interpreting recorded data about a social phenomenon to build
theories about that phenomenon. The technique was developed by Glaser and Strauss (1967)18
in their method of constant comparative analysis of grounded theory research, and further
refined by Strauss and Corbin (1990)19 to further illustrate specific coding techniques – a
process of classifying and categorizing text data segments into a set of codes (concepts),
categories (constructs), and relationships. The interpretations are “grounded in” (or based on)
observed empirical data, hence the name. To ensure that the theory is based solely on observed
evidence, the grounded theory approach requires that researchers suspend any preexisting
theoretical expectations or biases before data analysis, and let the data dictate the formulation
of the theory.
Strauss and Corbin (1998) describe three coding techniques for analyzing text data:
open, axial, and selective. Open coding is a process aimed at identifying concepts or key ideas

that are hidden within textual data, which are potentially related to the phenomenon of interest.
The researcher examines the raw textual data line by line to identify discrete events, incidents,
ideas, actions, perceptions, and interactions of relevance that are coded as concepts (hence
called in vivo codes). Each concept is linked to specific portions of the text (coding unit) for later
validation. Some concepts may be simple, clear, and unambiguous while others may be
complex, ambiguous, and viewed differently by different participants. The coding unit may vary
with the concepts being extracted. Simple concepts such as “organizational size” may include
just a few words of text, while complex ones such as “organizational mission” may span several
pages. Concepts can be named using the researcher’s own naming convention or standardized
labels taken from the research literature. Once a basic set of concepts are identified, these
concepts can then be used to code the remainder of the data, while simultaneously looking for
new concepts and refining old concepts. While coding, it is important to identify the
recognizable characteristics of each concept, such as its size, color, or level (e.g., high or low), so
that similar concepts can be grouped together later. This coding technique is called “open”
because the researcher is open to and actively seeking new concepts relevant to the
phenomenon of interest.
Next, similar concepts are grouped into higher order categories. While concepts may
be context-specific, categories tend to be broad and generalizable, and ultimately evolve into
constructs in a grounded theory. Categories are needed to reduce the amount of concepts the
researcher must work with and to build a “big picture” of the issues salient to understanding a
social phenomenon. Categorization can be done is phases, by combining concepts into
subcategories, and then subcategories into higher order categories. Constructs from the
existing literature can be used to name these categories, particularly if the goal of the research
is to extend current theories. However, caution must be taken while using existing constructs,
as such constructs may bring with them commonly held beliefs and biases. For each category,
its characteristics (or properties) and dimensions of each characteristic should be identified.
The dimension represents a value of a characteristic along a continuum. For example, a
“communication media” category may have a characteristic called “speed”, which can be
dimensionalized as fast, medium, or slow. Such categorization helps differentiate between
different kinds of communication media and enables researchers identify patterns in the data,
such as which communication media is used for which types of tasks.
The second phase of grounded theory is axial coding, where the categories and
subcategories are assembled into causal relationships or hypotheses that can tentatively
explain the phenomenon of interest. Although distinct from open coding, axial coding can be
performed simultaneously with open coding. The relationships between categories may be
clearly evident in the data or may be more subtle and implicit. In the latter instance,
researchers may use a coding scheme (often called a “coding paradigm”, but different from the
paradigms discussed in Chapter 3) to understand which categories represent conditions (the
circumstances in which the phenomenon is embedded), actions/interactions (the responses of
individuals to events under these conditions), and consequences (the outcomes of actions/
interactions). As conditions, actions/interactions, and consequences are identified, theoretical
propositions start to emerge, and researchers can start explaining why a phenomenon occurs,
under what conditions, and with what consequences.
The third and final phase of grounded theory is selective coding, which involves
identifying a central category or a core variable and systematically and logically relating this
central category to other categories. The central category can evolve from existing categories
or can be a higher order category that subsumes previously coded categories.
