❓ Frequently Asked Questions
What is election polling?
Election polling surveys a sample of voters to estimate public opinion on candidates or issues before an election.
How are election forecasts produced from polling data?
Forecasts combine poll results with past voting patterns, demographics, and turnout assumptions, typically using models and simulations to estimate win probabilities.
What is a postmortem in elections?
A postmortem is a retrospective analysis after an election to explain forecast accuracy, identify biases or data issues, and suggest improvements for future cycles.
Why do polls sometimes miss the final outcome?
Misses can occur from sampling errors, nonresponse bias, late-deciding or turnout-shifting voters, changing conditions after polling, and question design.
What does margin of error mean, and how should it be read?
The margin of error describes the range of uncertainty around a poll’s estimate due to sampling; the true value is likely within ±that amount, with a stated confidence level.
