Multiple Choice

Which of the following is TRUE?

• A) When sampling from a population that is highly skewed, a cluster sample generally provides the most representative sample.

However, this method generally produces less precise estimates of population values than simple random samples.
• C) In calculating the standard error of the mean when using a stratified sample, one finds that differences among strata means do not enter the estimate.
• D) When using proportional allocation in stratified random sampling, one samples from each of the strata in proportion to their respective variabilities.
• E) The sampling distribution of means for stratified sampling is generally less concentrated than that obtained from simple random sampling.
