Stratification, Clusters & Design Effects – Practice Quiz

Design and analyze stratified and clustered samples. Combine stratum estimates, allocate sample sizes, calculate design effects and effective sample sizes, and diagnose why an iid analysis can overstate the information in clustered observations. Practice progresses from concepts through worked applications to assumption checks and synthesis. Prerequisites: probability, sampling distributions and the preceding resampling curriculum. Includes single-select and multiselect practice with worked solutions and distractor analysis.
