2. 32. The average age of the

World Cup game:
When Germany played Iran
in the 1998 finals in France,

3. Mean
• The sum of all the values divided by
the number of values.

8 11 3
11
7+8+11+3+11 =
5
40 =

8

4. Median
• The median is the middle value
when they are arranged in size
order.
7
8 11 3
11
3 7 8 11 11

5. Mode
• The mode is the most common
value
7
8 11 3
11
3 7 8 11 11

6. Range
• The range is difference between
the highest and lowest value.
7
8 11 3
11
11 – 3 = 8

7. Find the mean, median and mode
ages of the team and the range
• MEAN
The sum of all the values divided by the
number of values.
• MEDIAN
The middle value when they are arranged in
size order.
• MODE
The most common value.
• RANGE
The difference between the highest and lowest
