A survey selects districts first, schools within those districts second, and students within the selected schools third. This design is called:
Correct answer: D. Multistage sampling
- A. Judgement sampling
- B. Quota sampling
- C. Simple random sampling
- D. Multistage sampling
Explanation
Multistage sampling selects samples through two or more successive stages. Selecting districts, then schools, then students is a clear multistage design, not a single-stage random method.

About Sampling and Estimation
Sampling covers population and sample, sampling frames, simple random, systematic, stratified, cluster and convenience methods, along with sampling and non-sampling errors. Estimation includes sample statistics, population parameters, point estimates, confidence intervals and margins of error, with attention to how sample size affects precision.

More Sampling and Estimation questions
A researcher selects participants because they possess specific expertise required for a study. Which sampling method is being used?
For a fixed sample size, which change generally reduces the margin of error of an estimate?
Under proportional allocation in stratified sampling, the sample size from each stratum is determined mainly by its:
A sample proportion is 0.40 and the sample size is 100. What is the approximate standard error of the sample proportion?
For a large population, what minimum sample size is required to estimate a population proportion with 95 percent confidence and a margin of error of 0.05 when no prior estimate of the proportion is available?
Among several unbiased estimators of the same population parameter, the most efficient estimator is the one with the:
