Calculation Method: Sheet • Enables metrology engineer use his/her existing uncertainty calculation budgets with Metrology.NET™ • Easy to operate with its simple interface • Allows the operator to follow the result and uncertainty for each of the test points The difference between the two is that STDEV.P is based on you supplying it with the entire population of values. To do this in Microsoft Excel, you will need to install Data Analysis Tool Pack. Work this out with: Relative uncertainty = (absolute uncertainty ÷ best estimate) × 100%. Estimating uncertainty can be a difficult task, especially if you are a beginner. 1 Excel could use the Normal equation to calculate Ù and did do so in earlier versions, but to obtain greater stability with some data sets it actually uses a different calculation method.
