WebJun 2, 2024 · Calculate the percent error of his measurement. Solution: Given, Measured area value = 450 cm² Actual area value = 455 cm² Steps of calculation, Step 1: Subtract one value from another; 455 – 450 = 5 the difference is 5, which is the error. Step 2: Divide the error by actual value; 5/455 = 0.0109 Step 3: Multiply this value by 100 WebJun 11, 2024 · The first thing you need to do is to subtract the accepted value from the experimental value. Or, in short, subtract one value from another. Note: Ignore any minus sign. Then, take the absolute value you got as a result of step 1. Now, you must divide that answer by the exact or ideal value.
