Homework-Due Monday, June 15th

Mode, Median, Mean and Range!
Your homework this week is to put into practise what you have been learning in the classroom.
For each of the set of numbers, you need to work out the mode, median, mean and range for EACH of them.

Remember– the first thing you need to do is to REARRANGE all the numbers in each group as you go.
Mode-which number you see that repeats?
Mean-+ and the divide.
Median- Middle number
Range- big number -little number

Do not copy one anothers work as it will soon be easy to see who has. The first few in each grade to be fully finished and correct will receive and prize. Good luck!

1) 21 , 15 , 18 , 11 , 13 , 7

2) 20 , 5 , 11 , 19 , 10 , 14 , 19

3) 7 , 10 , 11 , 3 , 20, 7, 7, 10

4) 8 , 16 , 18 , 10 , 9 , 6 , 17, 8, 18

5) 8 , 6 , 4 , 20 , 20, 2, 3, 15
