YEAR RETURN (X -Average Return of X)^2
1 12 0.111111
2 11 1.777778
3 16 13.444444
4 8 18.777778
5 13 0.444444
6 14 2.777778
Total 74 37.333333
Average Return = Total Return / NO of years
74 / 6
12.33
Variance = sum of (X -Average Return of X)^2 / no of years
37.333333 / 6
6.2222
Standard Deviation = Square root of Variance
Square root of 6.2222
