Edit: I guess if you really wanted to, you could make a UDF. alt+F11 opens the VB editor. Insert > Module and paste the code below in the window that opens. Public Function PercentError (byVal Expect As Long, byVal Actual As Long) As Double PercentError = Abs((Expect - Actual) / Expect) End Function The formula in C1 would then be =PercentError(A1,B1) Source(s): Elmyr · 8 years ago 0 Thumbs up 0 Thumbs down Comment Add a comment Submit · just now Report Abuse Add your answer Excel percent error function Is there a function in excel where i can calculate the percent error.

| Scientific Calculator | Statistics negative percent error Calculator In the real world, the data measured or used percent error formula chemistry is normally different from the true value. The error comes from the measurement inaccuracy or the approximation used https://answers.yahoo.com/question/index?qid=20080805065431AAZg9N2 instead of the real data, for example use 3.14 instead of π. Normally people use absolute error, relative error, and percent error to represent such discrepancy: absolute error = |Vtrue - Vused| relative error = |(Vtrue http://www.calculator.net/percent-error-calculator.html - Vused)/Vtrue| (if Vtrue is not zero) percent error = |(Vtrue - Vused)/Vtrue| X 100 (if Vtrue is not zero) Where: Vtrue is the true value Vused is the value used The definitions above are based on the fact that the true values are known. In many situations, the true values are unknown. If so, people use the standard deviation to represent the error. Please check the standard deviation calculator.

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 allows you http://www.wikihow.com/Calculate-Percentage-Error to compare an estimate to an exact value. The percentage error gives you the difference between the approximate and exact values as a percentage of the exact value and can help you see how close your guess or estimate was to a real value. If you want to know how to calculate percentage error, all you need to know is the approximate and exact percent error value and you'll be on your way. Steps 1 Know the formula for calculating percentage error. The formula for calculating percentage error is simple:[1]'[(|Exact Value-Approximate Value|)/Exact Value] x 100 The approximate value is the estimated value, and the exact value is the real value. Once you find the absolute value of the difference between the approximate value and exact value, all you need to do to calculate percentage is to divide it by the exact value and multiply the result by 100. 2 Subtract the real number from your number. This means that you should subtract the real value from the estimated value. In this case, the real value is 10 and the estimated value is 9. Ex: 10 - 9 = 1 3 Divide the result by the real number. Simply divide -1, the result when 10 is subtracted from 9, by 10, the real value. Place the fraction in decimal form. Ex:-1/10 = -0.1 4 Find the absolute value of the result. The absolute value of a number is the value of the positive value of the number, whether it's positive or negative. The absolute value of a positive number is the number itself and the absolute value of a negative number is simply the value of the number without the negative sign, so the negative number becomes positive. Ex: |-0.1| = 0.1 5 Multiply the result by 100. Simply multiply the result, 0.1, by 100. This will convert the answer into percent form. Just add the percentage symbol to the answer and you're done. Ex: 0.1
