Expert Answer:

When we talk about average, we usually refer to it as mean which is simply the sum of all the values divided by
the total number of items in that set. Mean is the central tendency, which refers to the central value or the typical (that is symbolic value) of the data.
 
size 12px The size 12px space size 12px mean size 12px space size 12px is size 12px space size 12px useful size 12px space size 12px for size 12px space size 12px predicting size 12px space size 12px future size 12px space size 12px results size 12px space size 12px when size 12px space size 12px there size 12px space size 12px are size 12px space size 12px no size 12px space size 12px extreme size 12px space size 12px values size 12px space size 12px in size 12px space size 12px the size 12px space size 12px data size 12px space size 12px set size 12px. size 12px space size 12px space
 
Example:

The marks of seven students in a mathematics test with a maximum possible mark of 20 are given below:
     15     13     18     16     14     17     12

Find the mean of this set of data values.

begin mathsize 12px style Mean space equals space fraction numerator 15 space plus space 13 space plus space 18 space plus space 16 space plus space 14 space plus thin space 17 space plus thin space 12 over denominator 7 end fraction space equals space 105 over 7 equals 15
Thus comma space mean space which space is space straight a space measure space of space central space tendency space focuses space on space where space the space data space is space centred space or space clustered.
We space find space the space mean space for space marks space in space straight a space class space to space know space that space value space around space which space most space of space the space students space scored. end style
