4.3 CHOICE OF METHODOLOGY
This section puts forward the rationale for the choice of a combined quantitative and
qualitative methodology in this study. Certain important factors were considered in the
choice of this methodology and these are presented in the following discussion.
4.3.1 Technical considerations
A combined quantitative and qualitative methodology was chosen mainly because the
two methods complement each other. The quantitative method, on the one hand has the
potential to gather a large amount of standardised information from several informants.
The standardisation of responses facilitates scoring and analysis and the method can be
used to obtain factual, less personal information (McMillan & Schumacher 1993:251).
On the other hand, qualitative method gathers in-depth and elaborate information from a
small purposefully sampled group of people. In this study this group is sampled from
similar respondents to those who completed the questionnaire thus increasing the
likelihood of obtaining reliable data. The qualitative method supplements the quantitative
one as it elicits information of a personal nature and allows the participants to express
feelings and opinions on issues which the questionnaire items do not allow. The VConf-
FGI was selected as the qualitative method of choice because it creates a social
environment in which group members are stimulated by each others’ perceptions and
112
ideas which increases the quality and richness of data (McMillan & Schumacher1993:
432). Moreover, the focus group method serves to cross validate data collected by means
of the questionnaire.
This combination of quantitative and qualitative methods in the design of the study is a
form of triangulation. The section which follows explains the concept triangulation.
4.3.1.1 Triangulation
According to McMillan and Schumacher (1993:498), triangulation is the cross validation
among data sources, data collection strategies, time periods and theoretical schemes. To
find regularities in the data, different sources, situations and methods are compared to see
if the same pattern keeps occurring. Flick (2002:227) characterises triangulation as a key
word used to name the combination of different methods, study groups, local and
temporal settings as well as different theoretical perspectives in dealing with a
phenomenon. It can mean combining several qualitative methods, but it can also mean
combining qualitative and quantitative methods (Flick 2002:265).
Flick (2002:227) explains that triangulation was first conceptualised as a strategy for
validating results obtained using individual methods. The focus, has however, shifted
towards further enriching knowledge and towards transgressing the always limited
epistemological potentials of the individual method. This way the two methodological
perspectives balance each other. They operate side by side (Neuman 2000:125), remain
autonomous and are seen as equal in their role in the project. They can function
simultaneously too (p125).
Flick (2002:227) refers to the strategy of integrating quantitative and qualitative methods
in one study as ‘methodological triangulation’. He distinguishes two types: within-
method and between-method. The within-method strategy might use different sub-scales
for measuring an item in a questionnaire, whereas the between-method strategy combines
the questionnaire with a semi-structured interview.
