Burns‚ N & Grove‚ S) stated that ‘In qualitative research‚ the focus is on the quality of the information obtained from a person‚ situation or event sampled rather than the size of the sample.’ Consequently using a small sample size means that the results cannot be reprehensive of the whole population but by using a small sample it costs less and is quicker to achieve (Burns‚ N & Grove‚ S 2007). The design of this study is a descriptive design; this type of design is aimed in gaining more information

This is particularly important in large‚ new and expensive studies. What appears to be a problem-free protocol may prove to have logistic and practical problems in implementation. A pilot study is a trial to pre-test the planned research on a small sample to determine its feasibility and practicality. Weaknesses in the research process then can be corrected while the plan is still flexible. Based on the outcome of the pilot study‚ the protocol may be modified before the study proper is implemented
