A simple random sample is always preferred because it obtains the same information as other sampling plans but requires a smaller sample size. True or False? When conducting a cluster sample, it is better to have fewer clusters with more individuals when the clusters are heterogeneous. True or False? Inferences based on voluntary response samples are generally not reliable. True or False? When obtaining a stratified sample, the number of individuals included within each stratum must be equal. True or False? Read more

Understand the Problem

The question comprises a series of true/false statements related to sampling methods in statistics. Each statement concerns concepts such as simple random samples, cluster samples, voluntary response samples, and stratified samples, asking the respondent to evaluate the validity of these claims.

More Information

A simple random sample may not require the smallest sample size. Cluster sampling with fewer heterogeneous clusters improves representativeness. Voluntary response samples are often biased. Stratified sampling does not require equal numbers in each stratum.

Tips

A common mistake is assuming all sampling techniques are interchangeable or have the same efficiency.
