❖ To find the mean, add up all the numbers and divide by the amount of numbers there are. To find the range, subtract the highest number by the  lowest number in the data set.

2. Mean = 35  Range = 78

3. Mean = 43  Range = 58

4. Mean = 63  Range = 73

5. Mean = 61   Range = 56

6. Mean = 55  Range = 83

7. Mean = 61   Range = 53

8. Mean = 60  Range = 75

9. Mean = 50  Range = 76

10. Mean = 50  Range = 81
