The percent error formula
WebbPercentage error = V observed – V true V true × 100% For example, if the observed value is 56.891 and the true value is 62.327, the percentage error is: 56.891 – 62.327 62.327 … Webbcombine in different ways. When values with errors that are dependent are combined, the errors accumulate in a simple linear way. If the errors are independent, then the randomness of the errors tends, somewhat, to cancel out each other and so they accumulate in quadrature, which means that their squares add, as shown in the …
