what is the formula for the production volume variance?
442696
It compares the actual overhead costs per unit that were achieved to the expected or budgeted cost per item. The formula for production volume variance is as follows: Production volume variance = (actual units produced - budgeted production units) x budgeted overhead rate per unit.

To compute VP-P from the RMS voltage, the RMS voltage is multiplied by 2.8284. To compute VP-P from the average voltage, the average voltage is multiplied by 3.14159. A user enters the voltage, V and the result will automatically be calculated and shown.

The variance is the average of the squared deviations from the mean, i.e., var = mean(abs(x - x. mean())**2) . The mean is normally calculated as x. sum() / N , where N = len(x) .

Divide the total number of units produced by the actual operating time to get the average production rate for your equipment. Multiply the total downtime by your average production rate to find the total number of units you failed to produce during planned production hours.

Unlike the previous measures of variability, the variance includes all values in the calculation by comparing each value to the mean. To calculate this statistic, you calculate a set of squared differences between the data points and the mean, sum them, and then divide by the number of observations.

By the formula, 1/(1-. 1707) = 1.21, our VIF. If you take the square root of the variance inflation factor, that value tells you how much larger the standard error is compared to if that predictor was uncorrelated with any other predictor.
