Entrance poll

An entrance poll is a poll that is taken before voters have cast their votes at the polling stations. It is akin to an opinion poll in the sense that it asks who the voter plans to vote for or some similar set of questions. The possibility that the prospective voter might change his mind after the poll is very small compared to that of an opinion poll, therefore the margin of error of an entrance poll is expected to be lower than that of an opinion poll. However, the methodology of conducting an entrance poll is closer to that of an exit poll, where actual voters are being queried as opposed to potential voters in an opinion poll.

Entrance poll result estimates can be obtained very quickly as people can be interviewed earlier and more quickly, as opposed to exit polls. However, these polls are possibly subject to higher margins of errors compared to exit polls as early voters are given a higher preference than in exit polls.
