Percent Error

posted Aug 28, 2014, 7:18 AM by Marschal Fazio

A measure of how inaccurate a measurement is, standardized to how large the measurement is. Found by the formula (measured value-actual value)/actual value*100%. Depending on the degree of accuracy or precision, the level of acceptable error in a measurement may very. Typically for a high school chemistry experiment an error of less than 1% is acceptable. In our case in biology for population sampling, we will use an error of less than 5% as being very accurate.
