I am not sure what you are looking for but let me guess:
If you measure, say temperature of a liquid with a thermometer and you get a value t and the actual value is T, the error is T - t and the % error is T - t / T multiplied by 100.
Only a few instances will be there where T is predefined, like the melting point of ice and the boiling point of water.

((lab result - known) / known) * 100%
If the lab result is less then then known then you get a negative value for the difference. ie. a certain percentage decrease, vice versa.

It depends on the quality of your lab equipment and the conditions of your experiment.
If you have perfect conditions and perfect equipment you will not have any difference.
