About Polling Margin of Error Calc

This app helps make sense of election polling. Use it to compare the precision of polls, or to calculate the sample size required to produce a given margin of error.

It will also perform a hypothesis test and calculate a p value, given the null hypothesis that neither candidate is ahead. In other words, it will tell you how much confidence you should have in polling results.
