Variance is a measure of how data points differ from the mean. According to Layman, a variance is a measure of how far a set of data (numbers) are spread out from their mean (average) value. Variance means to find the expected difference of deviation from actual value. Therefore, variance depends on the standard deviation of the given data set.To calculate the cost variance for the business's graphic design budget, you would subtract the actual cost ($80,000) from the budgeted (or projected) cost ($60,000) for a cost variance of -$20,000.
