## What Is The Formula For Calculating Percent Error

Answer this question Flag as... EDIT Edit this Article Home » Categories » Education and Communications » Subjects » Mathematics » Probability and Statistics ArticleEditDiscuss Edit ArticleHow to Calculate Percentage Error Community Q&A Calculating percentage error You look up the density of a block aluminum at room temperature and find it to be 2.70 g/cm3. Of all of the terms below, you are probably most familiar with "arithmetic mean", otherwise known as an "average".

What is your percent error?Solution: experimental value = 8.78 g/cm3 accepted value = 8.96 g/cm3Step 1: Subtract the accepted value from the experimental value.8.96 g/cm3 - 8.78 g/cm3 = -0.18 g/cm3Step 2: Take And we can use Percentage Error to estimate the possible error when measuring. Typically, you hope that your measurements are all pretty close together. Calculating Percent Difference Here is how to calculate percent error, with an example calculation.Percent Error FormulaFor many applications, percent error is expressed as a positive value.

Note, this calculator uses the absolute value method for error calculation. Calculating Standard Deviation Determine, for each measurement, the error, percent error, deviation, and percent deviation.
