Non-Response Assessor

This tool estimates how JFK's 1963 approval rating might change if you replaced a subset of survey respondents with people showing different approval levels. It helps simulate the effects of differential nonresponse on public opinion findings.

How to use this tool:

  1. Adjust the sliders to choose how many respondents to replace and their expected approval rate.
  2. Click "Run Simulation" to update the predicted approval rate and confidence intervals.
  3. Compare the original and simulated outcomes visually and statistically.
  4. Press the reset button to test a new scenario or just change your specifications.
