BETHLEHEM, PA. — Every Tuesday, Chris Borick, director of the Muhlenberg College Institute of Public Opinion, sits down with LehighValleyNews.com politics reporter Tom Shortell for Lehigh Valley Political Pulse on WLVR.
They discuss the latest trends emerging from science-based polls to break down local, state and national campaigns and issues.
This week, the two tackle an important question: How many people do you need to hear from to make a poll scientifically accurate?
"In an election season, we focus so much on the races, the substance, the issues which, of course, are paramount," Borick said.
"But from a polling perspective, understanding how this art science is conducted always is great."
Borick said sample size is one aspect of polling methodology that affects the likelihood that the estimates in a poll reflect the population.
As the sample size gets bigger, the chances of error become smaller and smaller.
