This problem will help students to understand the concept of a probability distribution: various results are possible, and each result occurs with a certain probable frequency. It will help students to understand that even though each part of a random process is unpredictable, a large sample of data contains predictable patterns.
This activity works particularly well if students have access to computers or tablets so that they can use built-in statistical techniques. The data is presented in a GeoGebra worksheet, and is also available as a csv file.
Alternatively, you could print off Data Matching and cut out the cards for students to group.
Invite students to work in pairs to analyse the data sets, write down what they notice, draw any appropriate diagrams or work out summary statistics. Once they have grouped the sets, bring the class together to discuss the reasoning behind their grouping. Encourage them to present their arguments as clearly as possible. Do the others agree or disagree? Can the others refine their argument?
Once the cards are sorted, students could suggest the probability distributions from which the cards were drawn.
