3.1.2 Researchers Examine Data Critically
Researchers examine data and their sources critically. Good researchers go to great lengths to get
systematic, valid and reliable data. The researcher's aim is to interpret and understand the data.
This interpretation and understanding is based largely on the researcher's knowledge of existing
theory and current literature, as well as the researcher's personal experiences and perspectives.
3.1.3 Researchers Generalise and Specify Limits on their Generalisations
It is the aim of research to obtain valid generalisations. These generalisations can be established
most effectively through the development of explanatory theory as it is the application of theory that
tums fact-finding into research.
In this chapter the research methodology will be discussed. Leedy (1997: 104) defines
methodology as merely an operational framework within which the data is placed so that its
meaning may be seen more clearly. The research design and method will be discussed, as well as
the measuring instruments used to collect the data. There will be an overview of the sample design
and sampling methods, whereafter the data collection methods, data capturing, data editing and
data analysis will be discussed in detail. The chapter will be concluded with an overview of the
shortcomings and sources of error of the research project
3.2 RESEARCH DESIGN
Mouton (2001: 55) states that research design is a plan or blueprint of how the researcher intends
conducting the research. Research designs are tailored to address different kinds of questions or
problems. It is therefore logical to assume that the research design will have the research problem
as apoint of departure.
