We can also use a theoretical value (when it is well known) instead of an exact value. Excluded sections are 12.3*, 13.4, 15.3, 16.4, 17.4, 18.3, 18.4, 18.5, 19.4, 19.5, 20.3. *We learned about percent yield but excluded limiting and excess reagents. It is the use of the words "of" and "less/more than" that distinguish between ratios and relative differences.[4] See also Approximation error Errors and residuals in statistics Relative standard deviation Decibel For example, you would not expect to have positive percent error comparing actual to theoretical yield in a chemical reaction.[experimental value - theoretical value] / theoretical value x 100%Percent Error Calculation
