adopted a probabilistic sampling technique to select respondents for inclusion in the community based survey component. The literature suggests a choice of four possible probability sampling designs. Choosing of any brings along certain advantages and disadvantages. These probability sampling designs includes: the simple random sampling‚ stratified sampling‚ systematic sampling‚ and cluster sampling (Robson 2002; Doherty 1994). This study opted for the simple random sampling technique to select participant

If it were zero‚ what would this mean? Sampling error is the difference between the statistic estimated from a sample and the true population statistic. While we would expect the sampling error to not be zero‚ it is not impossible. For example if you were evaluating the ethnicities of a population and everyone
