# What Is The Scientific Formula For Percent Error

## Contents

The true value is the textbook/literature value. Solve for the measured or observed value.Note due to the absolute value in the actual equation (above) there are two solutions. The result of the difference is positive and therefore the percent error is positive. Without "Absolute Value" We can also use the formula without "Absolute Value". http://3cq.org/percent-error/what-is-percent-error-formula.php
