Reducing sampling variability can enhance the precision of epidemiological estimates. Strategies to achieve this include:
1. Increasing Sample Size: Larger samples reduce variability and yield more precise estimates. 2. Stratified Sampling: Dividing the population into subgroups (strata) and sampling within each subgroup can ensure that all segments of the population are adequately represented. 3. Repeated Sampling: Conducting multiple studies or surveys and combining their results can average out the variability.
