WebDuring receipt into inventory, inventory is valued at either purchase order price, including tax and any landed cost charges, or standard. Any differences between the standard cost and the purchase order price are expensed as a purchase price variance. The standard deviationis derived from variance and tells you, on average, how far each value lies from the mean. It’s the square root of variance. Both measures reflect variabilityin a distribution, but their units differ: 1. Standard deviationis expressed in the same units as the original values (e.g., meters). 2. Varianceis … See more Different formulas are used for calculating variance depending on whether you have data from a whole population or a sample. See more The variance is usually calculated automatically by whichever software you use for your statistical analysis.
