In an experiment observing a parameter with an accepted value of V A and an observed value V O, there are two basic formulas for percent accuracy: (V A - V O)/V A X 100 = percent accuracy (V O - V A)/V A x 100 = percent accuracy. If the observed value is smaller than the accepted one, the second expression produces a negative number. It's easy to avoid this, but in some cases, negative values
