1 Penalty shooting competition

2 Each person had 10 tries at shooting a penalty. These are their scores...

3 PlayerNumber of goals Player 15 Player 25 Player 32 Player 48 Player 59 Player 65 Player 76 Player 86 Player 98

4 Now lets put them in order from the smallest number of goals to the largest

5 PlayerNumber of goals Player 32 Player 65 Player 15 Player 25 Player 86 Player 76 Player 48 Player 108 Player 59

6 Number of goals

7 Which was the most common number of goals scored? 5 This is called the MODE

8 Number of goals When they are all lined up in order, which score is in the middle? 6 This is called the MEDIAN

9 The mean If we took all those goals and shared them out equally between the players, how many would each player have scored? = 54 Divide this by the number of players: 54 ÷ 9 = 6 This is called the MEAN

10 To find the mean, add up all the numbers, then divide by the number of numbers. Try this one... The mean

11 Find the mean of 10, 12, = 30 ÷ 3 = The mean of 10, 12 and 8 is 3 What is the median of those three numbers? 10

12 Find the mean of these sets of numbers 1. 3,5,5, ,2,3,9,6 3. 7,7,6, ,30,40, ,2,2,4,3,5,

13 Find the median of these sets of numbers 1. 3,5,7,7, ,2,3,9,4 3. 7,7,6,4, ,30,60,40, ,2,2,4,3,5,
