Solution

Dear student,
The mean is the average of the numbers.
It is easy to calculate : add up all the numbers, then divide by how many numbers there are. In other words it is the sum divided by the count.
Mean = $\frac{S u m o f a l l v a l u e s o f t h e d a t}{N o . o f i t e m s i n t h e d a t a}$
