While checking the accuracy of a portable spirometer for volumetric measures with a calibrated super syringe, you obtain a mean measured value of 2.7 L. What is the percent error of this instrument?

Question

Percent error is calculated using the formula: [(|True Value - Measured Value|) / True Value] * 100%. Assuming the true value is the standard 3 L for a calibrated super syringe, the percent error = [(|3 - 2.7|) / 3] * 100% = 10%.
