possible outcome. (3)Standard Deviation of Return: Risk refers to the dispersion of a variable. It is commonly measured by the variance or the standard deviation. The variance of a probability distribution is the sum of the squares of the deviations of actual returns from the expected return‚ weighted by the associated probabilities. 2 = ∑ p(i)*{*R(i)-E(R)]} 2 where‚ 2 =variance‚ R®=return for the ith possible outcome‚ p(i)=probability
