To calculate the mean, you need to add up the total of a set
of data (in this case, the total number of goals scored) and
then divide by how many numbers there are (in this case
there are 5 teams, so there are 5 numbers)

To calculate the mean, you need to add up the total of a set
of data (in this case, the total number of goals scored) and
then divide by how many numbers there are (in this case
there are 5 teams, so there are 5 numbers)
Total number of goals scored = 34 + 24 + 33 + 27 + 24
= 142

To calculate the mean, you need to add up the total of a set
of data (in this case, the total number of goals scored) and
then divide by how many numbers there are (in this case
there are 5 teams, so there are 5 numbers)
Total number of goals scored = 34 + 24 + 33 + 27 + 24
= 142
Mean = 142 ÷ 5
= 28.4

The mode is the value that appears the most often.
You will notice that MOde and MOst both start with the letters MO.
This may help you to remember what it means

The median is the middle value. To work it out, you must first put all
the numbers, in this case the number of goals scored, in order:

The median is the middle value. To work it out, you must first put all
the numbers, in this case the number of goals scored, in order:
24, 24, 27, 33 34

The median is the middle value. To work it out, you must first put all
the numbers, in this case the number of goals scored, in order:
24, 24, 27, 33 34
Then look for the middle value. So, in this case the median = 27

To work out the range, you find out the difference between the
smallest number (24) and the biggest number (34).
34 – 24 = 10
The range is 10
