An opinion poll, sometimes simply referred to as a poll, is a human research survey of public opinion from a particular sample.
Opinion polls are usually designed to represent the opinions of a population by conducting a series of questions and then extrapolating generalities in ratio or within confidence intervals.
A polling place is where voters cast their ballots in elections.
The phrase polling station is also used in American English and in British English, although polling place is the building and polling station is the specific room (or part of a room) where voters cast their votes. A polling place can contain one or more polling stations.
Since elections generally take place over a one- or two-day span on a periodic basis, often annual or longer, polling places are usually located in facilities used for other purposes, such as schools, churches, sports halls, local government offices, or even private homes, and may each serve a similar number of people. The area may be known as a ward, precinct, polling district or constituency. The polling place is staffed by officials (who may be called election judges, returning officers or other titles) who monitor the voting procedures and assist voters with the election process. Scrutineers (or poll-watchers) are independent or partisan observers who attend the poll to ensure the impartiality of the process.
