Answer:
Option A - 0
Step-by-step explanation:
Given : Data set {22, 8, 10 ,18 ,12, 20}
To find : What is the difference between the mean and the median of the data set?
Solution :
Data set in increasing order {8, 10 ,12,18, 20,22}
Mean is defined as the division of sum of set values by total number of values.
Substitute the values we get,
So, The mean of the set is 15.
Median of even numbers is the average of two middle terms.
So, The median of the set is 15.
Now, The difference of the mean and the median of the set is
Therefore,Option A is correct.
The difference of the mean and the median of the set is 0.
