Propagation of Errors - The Fact Factor

In statistics, mean absolute error (MAE) is a measure of errors between paired observations expressing the same phenomenon. Examples of Y versus X include comparisons of predicted versus observed, subsequent time versus initial time, and one technique of measurement versus an alternative technique of measurement. MAE is calculated as the sum of absolute errors divided by the sample size: WebAbsolute Error Formula. The absolute error is the absolute value of the difference between measured and true values.
