  Mean or Arithmetis mean is the average of the given set of values or numbers.Mean give the central tendency value in given data.It is widely used in statistics and data analysis.

  For example, In a classroom,the students scored different range of marks and we are asked to find the average marks of the class for knowing the overall class performance,this can be found out using Mean

  i.e.average marks=sum of different marks scored by students divided with total strength of the class.

  Mean of the given series can be found out by formula

  Mean=Sum of all the numbers of series/Total number of numbers

  so,mean of the above series is (23+45+67+87+55)/5

  =277/5

  =55.4

  hence mean of the above given series is 55.4
