Disadvantage  of standard Deviation

It is not  easy  to understand  and calculate.

It gives  more  weight  to the extremes  and less  to the items   nearer to mean. Since the squares  of the  deviation of bigger size would  be proportionate greater than  which  are comparatively small. The deviation  2 and 6  are in the  ration of 1:3 but their squares 4 and 36 would  be in the  ration of 1.9.
