Consider the set of numbers where the number
The mode is the most frequently occurring observation.
So in this case Mode is 10.
Median is the value of the middle-most observation (s).
Now the total number of terms are
= 1+2+3+......+10
Since total number of terms is odd. So the term which is median
So the 28th term is 7. So,
Therefore,
Median - Mode=|7 - 10|
=3
