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:
“A more secret, sweet, and overpowering beauty appears to man when his heart and mind open to the sentiment of virtue. Then he is instructed in what is set above him. He learns that his being is without bound; that to the good, to the perfect, he is born, low as he now lies in evil and weakness.”
—Ralph Waldo Emerson (1803–1882)
“The last publicized center of American writing was Manhattan. Its writers became known as the New York Intellectuals. With important connections to publishing, and universities, with access to the major book reviews, they were able to pose as the vanguard of American culture when they were so obsessed with the two Joes—McCarthy and Stalin—that they were to produce only two artists, Saul Bellow and Philip Roth, who left town.”
—Ishmael Reed (b. 1938)
“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)
