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 to compare an estimate to an exact value. The http://www.wikihow.com/Calculate-Percentage-Error percentage error gives you the difference between the approximate and exact values as a https://exceljet.net/formula/get-percent-change 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 value and you'll be on your way. Steps 1 Know the formula for calculating percentage error. The percent error 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 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 how to find 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 x 100 = 10% Community Q&A Search Add New Question How do I calculate a percentage error when resistors are connected in a series? wikiHow Contributor Carry the 2 and get the square root of the previous answer.

between two values in Excel, you can use a formula that divides the change itself by the "old" value. A classic example would be to calculate the percentage between sales last month and sales this month. How the formula works In the example, the active cell contains this formula: =(D6-C6)/C6 In this case, Excel first calculates the difference between the values (the actually change in sales) then divides that result by the original, or "old" value to get the decimal value -0.3435: =(49500-75400)/75400 =-25900/75400 =-0.3435 Because cell E6 is formatted using the Percentage number format (with no decimals), Excel displays the final result as -34% Author Dave Bruns Excel Formula Training Bite-sized videos in plain English.
