Stratified sampling is the best choice when the population is skewed and divided into portions. This technique involves dividing the population into homogeneous groups or strata and then selecting a random sample from each stratum. This ensures that each subgroup is well represented in the sample and helps in achieving high statistical efficiency. Other sampling techniques like simple random sampling, systematic sampling, and cluster sampling are not as effective when working with skewed populations.
