Here are the number of goals that 5 teams have scored so far this season: Team Goals Scored

Here are the number of goals that 5 teams have scored so far this season: Team Goals Scored

Cardiff 34Swansea 24Derby 33Coventry 27Burnley 24

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)

Cardiff 34Swansea 24Derby 33Coventry 27Burnley 24

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 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

In this case, the mode is 24 as it appears the most often

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:

Cardiff 34Swansea 24Derby 33Coventry 27Burnley 24

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

If there is an even number of values, you add up the 2 middle numbers and then half the total.

If there is an even number of values, you add up the 2 middle numbers and then half the total.

For example, to find out the median of the scores of just Cardiff, Swansea, Derby & Coventry:

If there is an even number of values, you add up the 2 middle numbers and then half the total.

For example, to find out the median of the scores of just Cardiff, Swansea, Derby & Coventry:

Put the scores in order: 24, 27, 33, 34

If there is an even number of values, you add up the 2 middle numbers and then half the total.

For example, to find out the median of the scores of just Cardiff, Swansea, Derby & Coventry:

Put the scores in order: 24, 27, 33, 34

Add up the 2 middle scores: 27 + 33 = 60

If there is an even number of values, you add up the 2 middle numbers and then half the total.

For example, to find out the median of the scores of just Cardiff, Swansea, Derby & Coventry:

Put the scores in order: 24, 27, 33, 34

Add up the 2 middle scores: 27 + 33 = 60

Then find a half of 60, which = 30

To work out the range, you find out the difference between the smallest number (24) and the biggest number (34).

To work out the range, you find out the difference between the smallest number (24) and the biggest number (34).

34 – 24 = 10The range is 10
