Strengthen the credibility of your survey-based research with this online seminar on the foundational principles of survey design, led by Adam Berinsky of the MIT Political Experiments Research Lab. Designed for PhD students and professional researchers, the seminar explores how sampling, question wording, response options, survey mode, nonresponse, weighting, and cognitive response processes shape the validity of empirical claims. Participants will learn how to identify and avoid common sources of bias, improve questionnaire design, develop effective pretesting strategies, and integrate transparent survey design decisions into manuscripts, grant proposals, and reproducible workflows. With examples from historical polling errors and contemporary applied research, the seminar offers both conceptual depth and practical tools for producing stronger causal and descriptive inference across political science, psychology, sociology, public policy, and related fields. The seminar is delivered live via Zoom, with recordings, slides, materials, and an expert-monitored Q&A forum available for 30 days afterward, and participants receive an official Instats certificate of completion. #OnlineSurvey #PoliticalScience #Psychology #PublicPolicy #SocialSciences #Sociology #SurveyDesign #DataScience #Statistics #Research #ResearchTraining #Instats
