If the gage … WebGage Bias Also known as Accuracy, Bias is an estimate of the error in the measurement system. Bias is estimated by taking repeat samples of a part or standard using the measurement system, and comparing the average of these measurements with a measurement taken of the same piece using equipment with higher accuracy.
