Limitations of the Research Study
Convenience sampling was chosen as the most viable sampling technique; therefore caution is warranted in the generalisability of the results. The survey was distributed through the researcher’s Facebook friends and friends of friends. Given the age of the researcher, the majority of the sampled respondents occupy the 22–25 age group. However, every effort was made to access other age groups through friends of friends. A risk of response bias is possible because the survey was distributed through the researcher’s Facebook friends. Response error is also a possible limitation where social desirability might have been a guiding factor over honest and truthful remarks. Participants may have disclosed answers they believed the researcher wanted to hear. There is a risk of item response as a small number of survey respondents did not complete all answers on the survey; however because the number of missing values is so small it is unlikely to affect the overall results.
