Nonresponse, Calibration & Survey Uncertainty – Practice Quiz

Build a rigorous understanding of nonresponse, calibration & survey uncertainty through 20 original single-select and multiselect questions. Begin with core definitions, then work through calculations, assumptions, counterexamples and advanced diagnostic challenges.

Prerequisites: probability sampling, weighted means and elementary variance estimation.

Competencies: Distinguish frame coverage, unit nonresponse and item nonresponse; Assess response-rate and auxiliary-variable evidence; Compute poststratification and inverse-response weights; Explain marginal calibration and its support limits; Diagnose weight variability and design effects; Compute and interpret replicate-weight uncertainty; Evaluate trimming and adjustment uncertainty; Assess assumptions for nonprobability generalization. Every item includes a worked explanation and reasons for rejecting distractors.
