Forget apples, now we're the potentates of potato land

Discuss with students the concept of a representative sample and what can happen if a sample is not representative.

Issues that need to be raised include how the participants were selected, how many people participated, how the survey questions were structured, whether factors such as age, ethnicity and gender were considered, and whether the time of year the survey was conducted would influence results(eg. fruit seasons).

Use "teacher in role" to encourage students to ask questions about the survey material if the real information was not available.

Encourage students to identify the information which was not included. For example, how much fruit do Tasmanians currently eat and how much should they be eating?
