Question

What is the difference between the mean and the median of the data set?

{22, 8, 10 ,18 ,12, 20}

Answer 1

the mean is 15 and the median is also 15 so there is no difference

Explanation:

Answer 2

The difference is 0.

Explanation:

The given data set is

{22, 8, 10 ,18 ,12, 20}

The mean is given by;

`\bar X=(\sum x)/(n)`

`\bar X=(22+8+10+18+12+20)/(6)`

`\bar X=(90)/(6)`

`\bar X=15`

To find the median, arrange in order.

8, 10 ,18 ,12, 20,22

The median is the average of the two middle terms;

`(12+18)/(2)`

`=(30)/(2)=15`

Difference:

15-15=0
