ratios and proportions units, dimensions, and conversions logarithms arithmetic mean, error, percent error, and percent deviation just to name a few
If it's high that means it's very off and away from the actual value. If you find a low percent error it is very close or close to the true value.
the percentage of error in a chemistry experiment is over 60% because of the complexity of the chemistry it self and the steps can be easily mistaken and there for heading for failure.
The error in its area is then 2 percent....
Percent error is typically used to describe the difference between an expected value and an observed value (measured in an experiment). To calculate percent error, you must know the expected (or theoretical) value, determined from reference manuals and formulas. Percent error = [(actual measured value)/(expected value) - 1] x 100% Let's say that you do a chemistry experiment, where you expect to use 30 mL of a hydrochloric acid solution to neutralize a prepared solution of sodium hydroxide. When you perform the experiment, you actually use 30.2 mL of hydrochloric acid solution. Percent error = [(30.2 mL) / (30 mL) - 1] x 100% = 0.667 % error
