Calculate the standard deviation of each data set {10,10,10,10,10}  Choose the correct answer:  A) 8.05  B) 9  C) 10  D) 15  E) 15.5
Standard Deviation Data set 8.05   = √[ ( (9-10)2+(10-10)2+(11-10)2+(7-10)2+(13-10)2 )/5 ] = 2   Standard Deviation Data set B   = √[ ( (10-10)2+(10-10)2+(10-10)2+(10-10)2+(10-10)2 )/5 ] = 0   Standard Deviation Data set C   = √[ ( (1-10)2+(1-10)2+(10-10)2+(19-10)2+(19-10)2 )/5 ] = 8.05   Option 8.05
