Measures of average are also called measures of central aim. Their purpose is to tolerate a numerical figure which may describe the level of good distribution. For example let five students be awarded marks as follows. 10, 11,9,12 and 13. totally these gain ground are contrary from each other but at least there is one such score to which the rest of the scores standby or nearby.
