Please try the request again. We can also use a theoretical value (when it is well known) instead of an exact value. 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 Since the experimental value is smaller than the accepted value it should be a negative error.
