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 formula for calculating percentage error is simple:[1]'[(|Exact Value-Approximate Value|)/Exact Value] x percentage error definition 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 you should subtract the real value from the estimated value. In this case, the real value can percent error be negative 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.

withseveral important concepts based on numbers. The concept of percentage is one of the percent error worksheet them. The percentage is defined as the numberor the ratio which is represented in terms offraction of 100. The name "percent"
What Is A Good Percent Error
itself is made up of two words - "per" and "cent". Per means "each" or "every" and cent stands for "hundred". Thus, the term percent indicates "a quantity ineach hundred".The abbreviation "pct" or sometimes http://www.wikihow.com/Calculate-Percentage-Error "pc" (in economics) is used for the percentage. Most commonly, the sign "%" is used as apercent sign. The quantity of percentage has no dimension andit has no unit.The percent compares agiven numberwith what fractionis inevery 100.Let's say, a student obtained65% marks in exam. It means he would have secured 65 marks out of every 100 on an average. In this page below, we are going learn about a different http://math.tutorvista.com/number-system/percentage-error.html conceptabout the percentage. This concept is called "percentage error". Let us go ahead and understand definition of percentage error, method of calculating percentage error and examples based on it. Definition Back to Top The percentage error is defined as thepercentage ofthe difference between measured value and exact value. The measured value is also known as approximated value or experimental value. It is the value calculated by us. Exact value is also called theoretical value which is the value known by us. The percentage error is said to be the percent of theerror in exact value. It is calculated by dividing the error by hundred and making it percentage. The term "percent error" is also used in the same meaning.When thepercentage error is veryclosetozero, it indicates that the exact value is very close to the measured valuewhich is good and required for an experiment.The concept ofpercentage erroris often used in science-related subjects where the difference of experimental value and exact value is to be reported.It is used whenever itis important to know the amount of error in the data and it is necessary to know the cause of the error,whether it is due toour own mistake inestimations or by equipment impairment.The calculation of percentage error enables us tocompare
