Alternatively, researchers use it to compare a value from an experiment to a theoretical or true value to understand the validity of their experimental calculations. To calculate this type of measurement error, you must know the correct value. When you don’t know it, you’ll need to use another method, such as evaluating measurement variability.

The true value is 21; The difference between the values is found by subtracting the smaller value from the larger value. 26 – 21 = 5 and so, the difference between the measured and true value is 5. Step 2. Divide this result by the true value. The true value is 21 and so we divide 5 by 21. 5 ÷ 21 ≈ 0.238. Step 3. Multiply this result by 100
