A citizens' group wants to determine peoples' opinions about a new road. The members of the group conduct a survey at the largest mall in the city. Which best describes the sampling method used by the citizens' group?

convenience sample

random sample

self-selected sample

systematic sample

I think the correct answer from the choices listed above is the first option. The sampling method that the group used was convenience sampling. It is one of the main types of non-probability sampling methods. A convenience sample is made up of people who are easy to reach. Surveying in a mall is an example.
