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.
