A random sampling in the final phase was ensured, but the element of purposive sampling dominated.
In addition to random sampling, what other assumptions are violated in a study?
Selection of the study population was through random sampling.
The random selection of the clusters as the sampling units can be performed using simple random, systematic or stratified random sampling.
In all cases, the distribution is based on a random sampling of the 500 simulations to obtain 100,000 estimated r values.
Not only does this make the definition of a lot coherent, it makes testing more robust compared to non-simple random sampling.
Stratified random sampling was employed to select transect location by delineating 30 points 50 m apart on each of five trails in the study area.
Consequently, in the presence of clustering, the calculation of the variance of the prevalence using formulae for simple random sampling may yield overly optimistic estimates.
