Getting in Touch with Touchy Questions (UMAP)

A unit that involves probability and statistics with questionnaires. This module explains a bias-reducing technique called randomized response in which a chance mechanism is used to preserve the anonymity of particular respondents while enabling the surveyor to discover information about the group of respondents by using elementary probability concepts. Students use the randomized response models of Warner, Simmons, and Greenberg to analyze data collected in surveys.
