Distribution A:
X m = ( 11 + 12 + 13 + 14 +....+ 22 ) : 12 = 198 : 12 = 16.5 
s² ( A ) = ( 5.5² + 4.5² + 3.5² +.....+ 3.5² + 4.5² + 4.5² ) /11
Distribution B :
X m = ( 111 + 112 + 113 + .....+122 ) : 12 = 1398 : 12 = 116.5
s² ( B ) = ( 5.5² + 4.5² + 3.5² + ... + 3.5² + 4.5² + 5.5²) /11
s² ( A ) = s² ( B )
s ( A ) = s ( B )  -  standard deviations are the same.
