Qualitative Data Analysis

Qualitative analysis – the non-numerical examination
and interpretation of observations, for the purpose of
discovering underlying meanings and patterns of
relationship.
Linking Theory and Analysis

Cross-case analysis – an analysis that involves an
examination of more than one case; this can be either a
variable-oriented or case-oriented analysis.


Variable-oriented analysis – an analysis that describes and/or
explains a particular variable.
Case-oriented analysis – an analysis that aims to understand a
particular case or several cases by looking closely at the details
of each.

Qualitative Data Processing

Coding

– the initial classification and labeling of concepts in qualitative
data analysis.

– a reanalysis of the results of open coding aimed at identifying
the important, general concepts.

– building on the results of initial coding and the identification of
important, general concepts, identify the central concept that
organizes the other concepts that have been identified in a body
of textual materials.
