The formula for uncertainty can be derived by summing up the squares of the deviation of each variable from the mean then divide the result by the product of the number of readings and the number of readings minus one and then compute the square root of the result. I Find the average value of measured values. Calculating the uncertainty of a statistical value is helpful in a range of business applications such as evaluating customer feedback testing the quality of assembly line products and analyzing historical returns on a stock.
Total percentage uncertainty in V 3 x 04 12 Thus the result should be recorded as For uncertainty in the average value of many measurements.
Percent error is the difference between a measured or experiment value and an accepted or known value divided by the known value multiplied by 100. You get the relative uncertainty by dividing the absolute uncertainty with a measured value and multiplying by 100 to get percentage. Calculate the measure or reported value. Total percentage uncertainty in V 3 x 04 12 Thus the result should be recorded as For uncertainty in the average value of many measurements.
