A governor would like to find out how people in his state feel about state subsidized public art. How might a cluster sample be selected?
I searched Google under the key words "cluster sampling" to get these possible sources:

In the future, you can find the information you desire more quickly, if you use appropriate key words to do your own search.
I hope this helps. Thanks for asking.
To select a cluster sample for determining people's opinions on state subsidized public art, the governor can follow these steps:
1. Define the population: Determine the specific group of people in the state that the governor wants to survey. This could be all residents, registered voters, or any other specific demographic.
2. Identify clusters: Divide the state into smaller clusters or subgroups based on geographical regions. For example, the state can be divided into counties, cities, or zip code areas.
3. Randomly select clusters: Use a random sampling method to select a certain number of clusters from the identified clusters. The number of clusters selected should be proportional to the population size of each cluster.
4. Determine the sample size within each cluster: Decide on the number of individuals to survey within each selected cluster. This could be a fixed number for each cluster or a proportionate number based on the population size within the cluster.
5. Randomly select individuals within clusters: Use another random sampling method to select the individuals to be surveyed within each selected cluster. This can be done by assigning numbers (such as household numbers or resident IDs) within each cluster and randomly selecting individuals.
6. Conduct the survey: Once the sample has been selected, administer the survey to the selected individuals. This can be done through face-to-face interviews, phone interviews, online surveys, or a combination of methods.
By following these steps, the governor can obtain a cluster sample that represents the opinions of people in different regions of the state. This approach allows for more efficient data collection as it reduces the cost and time required to survey the entire population.
