Statistical Question Discuss what a statistical question is and give examples. Discuss various examples and non examples Have students work through a sorting activity in which they separate statistical and non-statistical questions Have students come up with their own real life situations and create their own statistical and non statistical questions Share out questions as a class and sort into the two categories
