The owner of a dance academy wants to know how many students would be interested in learning a rare tribal dance. Which sampling method will result in a sample that is not biased?

The owner talks to every third student entering a ballet class that is about to start.

The owner lists the names of all the students and calls every fifth student on the list.

The owner puts questionnaires in the changing rooms for students to fill out and drop into a secure box.

The owner questions students he personally knows because he thinks that they will speak honestly to him.
