take 31.2-24.5 (actual minus thought to be count). 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 I am doing a lab on finding the density of aluminum and iron metals. http://a1computer.org/percent-error/formula-for-percent-error-in-chemistry.php show more I am doing a lab on finding the density of aluminum and iron metals.

You look up the density of a block aluminum at room temperature and find it to be 2.70 g/cm3. If you need to know positive or negative error, this is done by dropping the absolute value brackets in the formula. In most cases, absolute error is fine. 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. Since the experimental value is smaller than the accepted value it should be a negative error.
