Chapter 3 Research Framework
3.9.2.1 Quantitative Computer-Assisted Data Analysis and Storage
Quantitative data can also be imported into a computer software package. The most
commonly used is the Predictive Analytics Software (PASW), formerly known as
Statistical Package for the Social Sciences (SPSS). PASW can handle complex
statistical procedures (Pallant, 2007). Watson, Atkinson and Egerton (2006: 135)
state that researchers rarely calculate results by hand now that computer packages are
available to do this “automatically and painlessly and with more precision and
accuracy”.
3.9.2.2 Rationale for quanitative data analysis approach used in this study
For the purpose of managing this research study’s questionnaire numerical data it
was decided that PASW could be used and that it would also serve to subject the data
to statistical testing.
Regardless of the approach to analysis (qualitative or quantitative) ensuring that the
research study and its findings are of a high quality is imperative for all researchers.
In the next section, the way the quality of the data can be assured and maintained
will be discussed.
3.10 Assessing and Maintaining Data Quality
Yin (2009) explained that in order to produce high quality data analysis in case study
research the researcher should use their own prior expert knowledge of the case
study topic in order to demonstrate an awareness of current thinking and discourse
about the case study topic. As advised by Yin (2009), a strategy for analysis must be
adopted to add to the validity and rigour of the study. A descriptive strategy can
develop the case description. This approach organises the case study, enables
analysis of embedded detail, and allows for explanation of implementations.
According to Saldana (2009), a descriptive strategy assists the reader to see what the
researcher saw and to hear what the researcher heard, thus reassuring the reader that
all of the evidence has been attended to. Furthermore, Schofield (2002) stated that
“studying the typical” contributes greatly to the validity of a case study and it
enhances its range of applicability. Yin (2009) defined the “typical” case as one that
captures the circumstances and conditions of everyday or commonplace situations.
