Gallup Poll Questions & Pew Research Findings

Gallup Poll Questions

Probability sampling: This approach gives every person in the population a known, non-zero chance of being selected. When samples are drawn with equal probability, each member is just as likely to be included, which helps reduce bias and makes the results more representative.
Random sample: A random sample is a subset where everyone has an equal shot at being chosen. One practical way to get this is to assign each person a number and use a random number generator to pick the needed respondents.
U.S. national sample size for �3% margin of error: To achieve a margin of error of about plus or minus three percentage points, you typically need roughly 1,000 respondents in a national survey.
Question wording: How a question is worded matters a lot. Wording can shape how people interpret and answer questions, so Gallup often tests different phrasings for new topics to improve clarity and reduce bias.

Primary media sources for election news: Cable news and newspapers are often listed as people�s primary sources, but television overall (network, cable, and local) remains the main source for about 75% of Americans.
Most useful media for grassroots participants: People involved in grassroots politics generally find newspapers the most useful.
Who turns to the Internet: Younger people and those with more education are increasingly using the Internet for campaign news.
Who relies on local TV news: Local television is especially important for African-Americans, lower-income households (under $20,000 a year), and people without a high school diploma.
Impact of political endorsements: Most Americans say endorsements don�t matter much�more than 60% report that endorsements, even from prominent figures like Colin Powell, don�t affect their vote.
