Calculate the percentage error between an experimental (observed) value and the theoretical (accepted) value.
| Experimental Value | — |
| Theoretical Value | — |
| Absolute Error | — |
| Percent Error | — |
% Error = |Experimental − Theoretical| / |Theoretical| × 100. Lower percent error = more accurate result. What counts as acceptable depends on the experiment, so check your instructor's or lab's tolerance.
