Cluster Sampling in AP Statistics

Cluster sampling divides a population into groups, randomly selects clusters, and collects data from every individual in the selected clusters.

What is Cluster Sampling?

Cluster sampling divides a population into groups, randomly selects clusters, and collects data from every individual in the selected clusters.

In AP Statistics, this term belongs to 1.11 Random Sampling. Use the notation and conditions attached to the procedure or model, then interpret the result in context.

Why Cluster Sampling matters in AP® Statistics

cluster sampling supports Unit 1: Exploring One-Variable Data and Collecting Data. The relevant CED learning objectives cover identify a sampling method given a description of a study; justify the appropriateness of a sampling method.

How Cluster Sampling connects across the course

1.11 Random Sampling

cluster sampling is used in this topic. Connect the definition to the topic's calculations and interpretations in context.

Simple Random Sample (Unit 1)

Simple Random Sample appears with cluster sampling in Topic 1.11. Use the two ideas together when a question moves from identifying the setup to interpreting the result.

strata (Unit 1)

strata appears with cluster sampling in Topic 1.11. Use the two ideas together when a question moves from identifying the setup to interpreting the result.

Is Cluster Sampling on the AP® Statistics exam?

An AP question can ask you to identify the study design or describe data with the correct graph and summary. Name the concept precisely, show the relevant calculation when needed, and state the conclusion in the problem's context.

Key things to remember about Cluster Sampling

• Cluster sampling divides a population into groups, randomly selects clusters, and collects data from every individual in the selected clusters.

• cluster sampling is mapped to 1.11 Random Sampling in the current AP Statistics course.

• On an AP question, use cluster sampling as part of a complete calculation or interpretation, not as an isolated label.
