A mutual fund has five equally likely outcomes: 15%, -7%, 5%, 2%, and -1%. Calculate the variance of the rate of return.
0.53%
0.26%
0.10%
0.14%
Variance =ΣP(X-X̅)^2 | ||||||
Where, | ||||||
X= Return | ||||||
X̅= Expected Return | ||||||
P = Probability | ||||||
P | X | X̅=P*X | (X - X̅)^2 i.e.(X-2.8)^2 | ΣP(X-X̅)^2 | ||
1 | 0.2 | 15.00 | 3.00 | 148.84 | 29.77 | |
2 | 0.2 | -7.00 | -1.40 | 96.04 | 19.21 | |
3 | 0.2 | 5.00 | 1.00 | 4.84 | 0.97 | |
