## Percentage Error Formula

Percent error -- take the absolute value of the error divided by the theoretical value, then multiply by 100. Example: I estimated 260 people, but 325 came. 260 − 325 = −65, ignore the "−" sign, so my error is 65 "Percentage Error": show the error as a percent of View all posts by Todd Helmenstine → Post navigation ← Direct Image Of Exoplanet Sets New Record Using Stem Cells and Herpes To Fight Brain Cancer → 3 thoughts on “Calculate Ex: |-0.1| = 0.1 5 Multiply the result by 100.
