Suppose you are conducting face-to-face surveys on community mental health across a large county without a master list of all residents. Applying the principles of cluster sampling, describe in one to three sentences how you would select your sample using towns as your clusters.
Question: Suppose you are conducting face-to-face surveys on community mental health across a large county without a master list of all residents. Applying the principles of cluster sampling, describe in one to three sentences how you would select your sample using towns as your clusters.
Sample answer: First, I would obtain a list of all towns in the county and randomly select a subset of these towns to serve as my clusters. Second, I would randomly sample individual residents from within only those selected towns to participate in the face-to-face surveys.
Key points:
- Randomly selecting a subset of towns (clusters) from the county list.
- Randomly sampling individual residents from within only those chosen towns.
Feedback: An ideal answer must specify: 1) randomly selecting a subset of towns (clusters) from the county list, and 2) randomly sampling individual residents from within only those chosen towns.

What is the defining procedure of cluster sampling?
A researcher wants to study the work-life balance of therapists across a large state using cluster sampling to minimize travel costs. Arrange the steps of this sampling process in the correct order.
A researcher is studying the mental health of nurses across a large state. Because they do not have a list of all nurses in the state, they randomly select 25 hospitals and then randomly select 12 nurses from each of those hospitals to interview. Match each element of this research plan to its role in the cluster sampling technique.
A researcher is investigating social interactions among preschoolers in a large city but does not have access to a central registry of every individual child. To address this, the researcher randomly selects 20 preschools and then randomly selects students from within those schools to participate.
True or False: In this scenario, cluster sampling is the only technique involving random selection that can be implemented without a complete list of every individual member of the population.
What is a primary logistical advantage of using cluster sampling for face-to-face interviews in psychological research?
Match each core aspect of the cluster sampling technique with its corresponding role or benefit within psychological research.
In a methodological evaluation, a researcher determines that _____ sampling is the most appropriate probability technique for a study when a comprehensive sampling frame of the entire population is unavailable, as it is uniquely the only probability method that does not require such a list.
A public health researcher studying depression prevalence in rural communities randomly selects 10 rural counties and then randomly surveys 40 residents from within each selected county. This study design qualifies as cluster sampling.
A researcher comparing probability sampling techniques concludes that simple random sampling, systematic sampling, and stratified sampling all require a complete list of every member of the target population—known as a _____—whereas cluster sampling is the only probability method that does not require one.
A researcher is evaluating whether cluster sampling is the best-justified probability method for a nationwide study on student well-being in which no master list of all students exists and face-to-face interviews are required across a large geographic area. Arrange the following evaluative steps in the order a researcher should logically complete them when making and justifying this methodological decision.
Define cluster sampling by describing its two-stage selection procedure, and explain the unique advantage it possesses regarding the sampling frame compared to all other probability sampling methods.
Explain why cluster sampling is the most appropriate probability sampling technique for this study, and describe how it resolves both the lack of a master list and the travel budget constraints.
