A group of students decide to do a survey to see how many students on Belmont’s campus are good piano players. They set up a table inside the Wilson Music Building from 9-11am on a Thursday. Four students are handing out small flyers with a number to text if you are a good piano player or if you are not. Now this survey is already set up to have a few different types of bias.

Text message which is a task that be easily forgotten and they also have to know that they are good piano play and respond truthfully. The use of voluntary response bias, nonresponse bias, and sampling bias makes this survey very inaccurate. It does not take into account a majority of the Belmont student
