Calculate the standard deviation for the following data: 13, 7, 7, 7, 7, 6, 6, 5, 5, 4, 4, 3

Expert Solution

Solution :-

n = 12

Mean = x / n

Mean = 74 / 12

Mean = 6.167

--------------------------------------------------------------------

Standard Deviation for Sample data is,

S = ( x - ) ^ 2 / ( n - 1 )

S = ( 71.667 / 12 - 1 )

s = 6.515

S = 2.55
