To find a median in any set, we have to arrange the set in ascending order.
Set A : 17 21 22 25 30
Set B : 14 15 19 20 30
Median is the middle value in any set, after arranging in ascending order.
Here Median for set A : 22 & for set B : 19
Difference = 22 - 19 = 3
Answer B
Set A : 17 21 22 25 30
Set B : 14 15 19 20 30
Median is the middle value in any set, after arranging in ascending order.
Here Median for set A : 22 & for set B : 19
Difference = 22 - 19 = 3
