Averages mystery

This averages mystery requires students to understand how to calculate the three averages (mean, median and mode) and the range from a list of numbers. Students need to work through a set of clues to determine who bit Sam, the vet’s assistant.

You could make this task easier by suggesting a starting point as clues are currently in random order.
