Suppose that the US imports widgets from the UK. The widgets cost $10 and £1 costs $1. Then the British Pound appreciates against the dollar and now £1 costs $1.50. Also suppose that the widgets now cost $12.5 There has been a 50% change in the exchange rate and a 25% change in price. The exchange rate pass-through is
Monte Carlo simulation allows the business risk analyst to incorporate the total effects of uncertainty in variables like sales volume, commodity and labor prices, interest and exchange rates, as well as the effect of distinct risk events like the cancellation of a contract or the change of a tax law.
Let us assume that standard direct material cost of widget is as follows: 2 kg of unobtainium at $ 60 per kg ( = $ 120 per unit). Let us assume further that during the given period, 100 widgets were manufactured, using 212 kg of unobtainium which cost $ 13,144. Under those assumptions direct material total variance can be calculated as:

Algorithms for calculating variance play a major role in computational statistics.A key difficulty in the design of good algorithms for this problem is that formulas for the variance may involve sums of squares, which can lead to numerical instability as well as to arithmetic overflow when dealing with large values.
Tolerance analysis is the general term for activities related to the study of accumulated variation in mechanical parts and assemblies. Its methods may be used on other types of systems subject to accumulated variation, such as mechanical and electrical systems.
Similarly, [1] [()] (′ ( [])) [] = (′ ()) (″ ()) The above is obtained using a second order approximation, following the method used in estimating ...
According to the PMBOK (7th edition) by the Project Management Institute (PMI), Cost variance (CV) is a "The amount of budget deficit or surplus at a given point in time, expressed as the difference between the earned value and the actual cost." [19] Cost variance compares the estimated cost of a deliverable with the actual cost. [20]
