Theoritical value = 350, Experimental Value = 250

Using the percent error formula, calculate the percent error in the guess value by the organizers. Therefore, the percent error in the estimation is 0.03%.Įxample 3: In a concert, 250 people were estimated to attend but 350 people attended. Percent Error = |(Experimental Value - Theoretical value) / Theoritical value| × 100 Theoritical value = 0.47in, Experimental Value = 0.5in

Find the percent error in the measurement. The actual value of the radius of the nut was known to be 0.47in. With Cuemath, find solutions in simple and easy steps.īook a Free Trial Class Examples Using Percent Error FormulaĮxample 1: The radius of a nut is measured as 0.5in. Use our free online calculator to solve challenging questions.

Step 3: Convert that decimal number into a percent by multiplying it by 100 and adding the percentage sign - %.

Step 2: Once we have obtained the value, divide it with the actual or theoretical value.

If the answer is negative, it converts into positive because of the absolute value sign.

Step 1: Using the percent error formula, subtract the experimental value from the theoretical value.

There are a few steps to be followed while calculating the percent error of a value, they are: Where, '| |' denotes the absolute value sign Percent Error = |(Experimental Value - Theoretical value) / Theoretical value| × 100 The Percentage or percent error formula of a given measurement can be expressed using the following expression. In mathematics, the percent error is always represented as a positive number.

The percent error formula is about comparing the estimated value with the exact value. The percent error formula calculates the absolute value of the difference between the measured value and the actual value that is divided by the actual value and multiplied by 100. In this section, we will learn about the percent error formula, and how to use it. The percent error formula is applicable to a wide range of scenarios, one might come across on a daily basis. The percent error formula helps us to calculate the exact amount of error that occurred in measuring the dimension or other quantities.
