How to read a poll
- Sample size is how many people were asked. More people means less random error, never none.
- ±3 is the margin of error: the real figure is likely within 3 points either way of the one shown.
- Two polls can differ because they were taken on different dates, with different methods and different samples.
- est. means the institute did not publish a margin of error, so it is estimated from the sample size.
- The average smooths this out: it combines recent polls, so one unusual poll cannot swing the picture.
