is the square root of the variance. The population standard devia¬tion is denoted by σ. Like the variance‚ the standard deviation utilizes the sum of the squared deviations about the mean (SSx). It is computed by averaging these squared deviations (SSX/N) and taking the square root of that average. One feature of the standard deviation that distin¬guishes it from a variance is that the standard deviation is expressed in the same units as the raw data‚ whereas the variance is expressed in those units

higher variance. If we compare both stocks‚ Reynolds is riskier than Hasbro in this case. The higher variance indicates higher chance that the actual return on Reynolds will deviate from the expected return.

Compute a materials price variance for the plates purchased last month and a materials quantity variance for the plates used last month. Materials Price Variance measures the difference between what is paid for a given quantity of materials and what should have been paid according to the standard. (Actual Quantity x Actual Price) – (Actual Quantity x Standard Price) or AQ (AP-SP) Materials Price Variance = 12‚000 plates x ($2.50 - $2.35) = $1‚800 Materials Quantity Variance measures the difference
