3.2 POPULATION AND SAMPLING
A population is the entire group of persons or objects that is of interest to the researcher, in other words, that meets the criteria which the researcher is interested in studying. (Brink & Wood 1998; Burns & Grove 2003).
The non-probability sampling approach was used within the XXX Metropolitan Province. Furthermore, the researcher used a convenience sampling technique which caused sampling bias. The researcher used the convenience sampling technique which was as a result of the readily available subjects for the study. (Brink, 2006:132). (Cohen, 2000) stated that the researcher simply chooses the sample from those to whom she/he has easy access. Cohen went on to say this implies generalisations of findings are limited as the sample does not represent any group other than itself. This is a limitation that is explained in the last section of this chapter. This creates a cause for further research to be done.
3.3 RESEARCH DESIGN
Qualitative and quantitative research designs were used. The research design describes the plan or blueprint of an investigation to obtain answers to research questions or problems (Babbie & Mouton, 2001). The researcher adopted the descriptive research technique. (Borg &Gall, 1989) say that, “descriptive research describes natural or man-made educational phenomena that are of interest to policy makers and educators.” For this reason the research design was chosen. Creswell and Brink alluded to the statement further when they noted that a descriptive research intends to present facts concerning the nature and status of a situation as it exists at the time of the study and to describe present conditions, events or systems based on the impressions or reactions of the respondents of the research. Moreover the descriptive design normally assumes there is insufficient existing literature, which was the case for
