In stratified sampling, the allocation problem refers to deciding how many sample units should be taken from each stratum to ensure efficient, accurate, and cost-effective results. The main factors influencing allocation include stratum size, variability, cost of sampling, and desired precision. There are three primary types of allocation:
1. Equal Allocation – Same sample size from each stratum, regardless of size.
2. Proportional Allocation – Sample size proportional to the stratum's population size.
3. Optimum Allocation – Considers both variability and cost to minimize sampling error and cost.
Understanding these allocation methods is essential for designing effective surveys and improving statistical accuracy.
