Quizplus · Accepted Answer

Disproportionate sampling is employed when the subpopulations have distinctive characteristics and their representation in the sample is crucial. Weighting is used to adjust for any imbalances in the sample composition, ensuring that each sample element is given the appropriate level of representation. These techniques are aimed at providing more precise estimates of population parameters and reducing bias in the sample. The ultimate goal is to achieve a representative picture of the total population despite the inherent complexities and challenges in the design of the study.
