How would you read these two formulas? The 1/4 and 1/6 are throwing me off. These are example problems from what I need to do.
Variance=1/4[(0.03 – 0.1)2 + (–0.14 – 0.1)2 + (0.27 – 0.1)2 + (0.22 – 0.1)2 + (0.12 – 0.1)2]
Geometric average return =[(1 + (0.17))(1 + (0.19))(1 + (0.18))(1 + (-0.09))(1 + (0.18))(1 + (0.11))](1/6) – 1
