An open access poll is a type of opinion poll in which a nonprobability sample of participants self-select into participation. The term includes call-in, mail-in, and some online polls.
The most common examples of open access polls ask people to phone a number, click a voting option on a website, or return a coupon cut from a newspaper. By contrast, professional polling companies use a variety of techniques to attempt to ensure that the polls they conduct are representative, reliable and scientific. The most glaring difference between an open access poll and a scientific poll is that scientific polls typically randomly select their samples and sometimes use statistical weights to make them representative of the target population.

Famous quotes containing the words open, access and/or poll:
“What is not in the open street is false, derived, that is to say, literature.”
—Henry Miller (1891–1980)
“The nature of women’s oppression is unique: women are oppressed as women, regardless of class or race; some women have access to significant wealth, but that wealth does not signify power; women are to be found everywhere, but own or control no appreciable territory; women live with those who oppress them, sleep with them, have their children—we are tangled, hopelessly it seems, in the gut of the machinery and way of life which is ruinous to us.”
—Andrea Dworkin (b. 1946)
“If Rosa Parks had taken a poll before she sat down in that bus in Montgomery, she’d still be standing.”
—Mary Frances Berry (b. 1938)
