  1. SurveyMan • Overall Project: automated design and management of online surveys using programming languages and systems concepts • Target Audience: Academic researchers, particularly in the Social Sciences • My Project: Quality Control – designing, implementing, and testing metrics to determine the quality of surveys and their responses Molly McMahon Advisor: Emery Berger Grad Mentor: Emma Tosch PLASMA Lab

  2. Quality Control Purpose: • Filter out random/lazy respondents Existing strategies: • Infrequency • Answer patterns • Inconsistent responses • Responses times My current work: Survey Entropy Metric Concepts used: Bootstrap resampling, Shannon Entropy, Welch’s t test

  3. Survey Entropy Metric • Given a survey and a list of responses, use bootstrapping to get resamples of the responses • Compute the entropy of each resampled list of responses, taking note of which original responses were not included in the resample • Compare the mean and standard deviation of all the resamples’ entropies to those of the resamples that did not include certain responses(Welch’s t-test) • If removing a certain response significantly lowers the survey entropy, response is an outlier
