Study design
In the second stage of the sampling procedure, homesteads (ultimate sampling units - USUs) were randomly sampled within selected dip-tank areas.
In order to adequately cover each dip-tank area, it was decided to sample as far as possible at least 10 homesteads per dip-tank area to give a total sample of 2,400 homesteads countrywide. This sample size (a sampling fraction of approximately 1.3%) is comparable to that normally used by the Central Statistical Office (CSO) in agricultural surveys.
The table shows the numbers of homesteads sampled within the sampled dip-tank areas of Sub-region 3 (Mayiwane) of the HHohho Region.
