Summary

In this activity, students form expert groups to learn about different sampling methods, then share their expertise in mixed groups. The mixed groups then analyze possible studies, considering how sampling could/could not be performed and what the most effective approach would be.

Learning Goals

Concepts and Content: Basic Sampling Methods for Statistical Studies
Higher-Order Thinking: analysis and synthesis of ideas; transfer of material to new situations
Other Skills: oral presentation, teamwork, written communication

Context for Use

This activity is designed for a class of approximately 18-30 students, but could be easily modified for other class sizes. No prerequisite knowledge is assumed. The activity is designed for one 75-minute class session; it could be modified for a single 90-minute session or two 50-minute sessions with the addition of more (or more complex) studies to analyze, or could be modified for a single 50-minute session by using fewer studies.

Teaching Notes and Tips

Students often struggle with the difference between stratified and cluster sampling, so pay particular attention to these expert explanations.

Assessment

Primary assessment: instructor listens to group discussions, giving general guidance and clarification as needed
Secondary assessment: instructor collects analyses from mixed groups, using group write-up to guide future instruction
