A community group would like to raise funds to pay for improvements to the community swimming pool. The group’s leaders are considering a number of methods to assess community interest in raising funds. Which of the following uses convenience sampling?

Convenience sampling means asking people who are readily available, rather than choosing them randomly. Standing outside a shopping center and asking people who enter is convenient, so choice B is correct. Randomly selecting homes, as in choice C, is random sampling; a webpage survey invites voluntary responses.
