For example the difference between a personâs score in group one and a personâs score in group two would represent explained variance. The âWithin Groupsâ variance represents what is often called âerror varianceâ. This is the variance within your groups, variance that is not due to the independent variable. For example, the difference between one person in group one and another person in group one would represent error variance. â From http://web.mst.edu/~psyworld/anovadescribe.htm. 1  Understand the concept of ANOVA.
The Volume variance represents the difference between the budget allowance and the standard expenses charged to work in process. If budget allowance is more than the standard expenses charged to production, the variance is called unfavorable volume variance. If budget allowance is less than the standard expenses charged to production, the variance is called favorable volume variance. Overhead volume variance is calculated when overall or net overhead variance is further analyzed using two variance method.
