Answer #1

One such reference is in news regarding new Ohio poll with Donald Trump having slight lead over Joe Biden, published on various websites. These news contain the margin of error. Margin of error is needed because a poll is conducted ona sample of data and not on the whole population. The sample statsitic would always differ from the population parameter. If a candidate is leading in polls with a percentage which is close to the margin of error, then that lead is not very relaible.
