AVERAGE(n1,n2,n3)

This function gives the Average for given set numbers.
Average means sum of all the given elements divided by Number of given elements.
It is also called Arithmetic mean. i.e if $n$ numbers are given and each number is denoted by ai, where $i=1$ to $n$ , then $A.M={\frac {1}{n}}\sum _{i=1}^{n}ai$ = 1/n(a1+a2+.....+an).
In this function N1,N2,... are either it can be numbers,arrays ,references of cells or
we can enter the logical values directly. This function will show .the result as Error ,
when the numbers are error values or text that cannot change in to numbers.
Also if the distribution is symmetric, then we can use this function to find the central tendency.
The three most common measures of central tendency are: A.M, Median,& Mode.A.M:
It is calculating by adding the given set of numbers and divided by the count of the given set of numbers. *E.g:Average of 2,4,2,7,2,3 and 5 is 3.6
Median: It is the middle number of a sorted list(Ascending order) of numbers.
E.g:The median of 2,2,2,3,4,5,7 is 3
Mode: It is the most frequently repeated number in a given set of numbers.
E.g.The mode of 2,2,2,3,4,5 and 7 is 2
