Consequences of Violating Randomization in Cluster Sampling

Jason Parrott & Shlomo Sawilowsky · Journal of Advances in Mathematics and Computer Science · 2014

Although not as efficient as simple random sampling, cluster sampling has been regarded as a valid sampling technique when the researcher is attempting to save cost. In order to do so, it is necessary that random selection occurs in all stages of sampling. This simulation study e...
