  The standard deviation is the average variation of the data values from the mean of the values and is the most commonly used measure of variation. ... There is more variation with Group2 – it has a larger standard deviation and a higher coefficient of variation. Group 2; Mean score = 64. SD = 9.

  SD(RP(A,BC)) = [0.52 × 0.25862 + 0.52 × 0.05952 + 2 × 0.5 × 0.5 × –0.001] = 0.1308. The risk-return trade-off can be calculated as the coefficient of variation (CV). This is defined as risk divided by expected return. A lower value for an investment implies a better risk-return trade-off. CV(A) = 0.2856 / …

  The coefficient of variation (CV) is a very useful measure when comparing the spread about the mean of two variables, particularly those that are in different units or scales. It is equal to the ratio of the standard deviation to the mean multiplied by 100%.
