Credit: Fuse N/A Getty Images Full Answer calculating percent error Percent error is useful in experiments and calculations involving known values; it provides a means of ascertaining the accuracy of calculations. Determining percent error is simple; subtracting the actual value from the experimental value, dividing by the actual value and multiplying the entire product by 100 yields percent error. A percent error of zero indicates that an experimental value is

exactly the same as the actual, accepted value. Percent errors are often positive with the difference between experimental and actual results being an absolute value. This is the case when it is important to determine error, but the direction of the error makes no difference. In some situations, however, the direction of the deviation is important. Chemistry, and some other sciences, maintain negative percent error values. For instance, a given reaction between two substances may have a previously published final yield. It is important for any scientists performing this reaction to report on its accuracy. It is also important to know the direction of the error. A positive percent error means that the reaction had a higher-than-expected yield while a negative error indicates a lower yield.

HOME CONTACT PERCENT ERROR You MUST use the percent error formula below when performing negative percent error percent error calculations for your lab reports. This version of the formula indicates whether your experimental value is less than or greater than the true value. If it is less than the true value, the percent error will be negative. If it is greater than the true value, the percent error will be positive. (experimental value) − (true value) % error = ――――――――――――― × 100 true value Remember, experimental value is what you recorded/calculated based on your own experiment in the lab. The true value is the textbook/literature value. You're hoping that if everything goes perfectly in lab (which almost never happens), your experimental value will be very close to the true value.
