Answer:
The difference is 0.
Step-by-step explanation:
The given data set is
{22, 8, 10 ,18 ,12, 20}
The mean is given by;
[tex]\bar X=\frac{\sum x}{n}[/tex]
[tex]\bar X=\frac{22+8+10+18+12+20}{6}[/tex]
[tex]\bar X=\frac{90}{6}[/tex]
[tex]\bar X=15[/tex]
To find the median, arrange in order.
8, 10 ,18 ,12, 20,22
The median is the average of the two middle terms;
[tex]\frac{12+18}{2}[/tex]
[tex]=\frac{30}{2}=15[/tex]
Difference:
15-15=0
