Explanation: Standard deviation indicates how different are the elements in the set. If the elements are close to each other, then the standard deviation is close to zero (it is zero only if the elements are identical). The bigger standard deviation, the more different elements in the set Example 1 Let the set be: S1={1,2,2,2,3} The mean is: x=1+2+2+2+35=105=2 The standard deviation is: σ=(12)2+3(22)2+(32)25 σ=1+15=250.632 Example 2 Let the set be: S2={0,1,2,3,4} The mean is: x=0+1+2+3+45=105=2 The standard deviation is: σ=(02)2+(12)2+(22)2+(32)2+(42)25 σ=4+1+1+45=105=21.414
