Question

Quizplus · Accepted Answer

Stratification involves dividing the population into relatively homogeneous groups, or strata, based on certain characteristics, such as age or income level. Each stratum is then sampled separately, which reduces the required sample size and increases the precision of estimates. Ratio estimation and difference estimation are techniques used for calculating population parameters, and MUS sampling is a type of probability sampling method.
