1. Penalty shooting competition

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

3. Player
Number of goals
Player 1 5
Player 2
Player 3 2
Player 4 8
Player 5 9
Player 6
Player 7 6
Player 8
Player 9

4. Now let’s put them in order from the smallest number of goals to the largest

5. Player
Number of goals
Player 3 2
Player 6 5
Player 1
Player 2
Player 8 6
Player 7
Player 4 8
Player 10
Player 5 9

6. Number of goals 2 5 5 5 6 6 8 8 9

7. 5 2 5 5 5 6 6 8 8 9 Number of goals This is called the MODE
Which was the most common number of goals scored?
This is called the MODE

8. 6 2 5 5 5 6 6 8 8 9 Number of goals This is called the MEDIAN
When they are all lined up in order, which score is in the middle? 6
This is called the MEDIAN

9. 54 6 2+5+5+5+6+6+8+8+9= The mean This is called 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. The mean
To find the mean, add up all the numbers, then divide by the number of numbers.
Try this one...

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