Quizplus · Accepted Answer

In stratified random sampling, the population is first divided into homogenous subgroups or strata based on some relevant characteristic. Then, within each stratum, a random sample is drawn. This method ensures that each subgroup of the population is represented in the sample, and also reduces the variability in the sample by ensuring that subgroups with unique characteristics are adequately represented in the sample. Therefore, the correct answer is C, where elements are sampled randomly from within these strata.
