Percent error or percentage error expresses as a percentage the difference between an approximate or measured value and an exact or known value. It is used in chemistry and other sciences to report the difference between a measured or experimental value and a true or exact value. Here is how to calculate percent error, with an example calculation.Percent Error FormulaFor http://chemistry.about.com/od/workedchemistryproblems/a/percenterror.htm many applications, percent error is expressed as a positive value. The absolute value of the error is divided by an accepted value and given as a percent.|accepted value - experimental value| \ accepted value x 100%Note for chemistry and other sciences, it is customary to keep a negative value. Whether error is positive or negative is important. For example, you would not expect to have positive percent error comparing actual to theoretical yield in a chemical reaction.[experimental value - theoretical value] / theoretical value x 100%Percent Error Calculation StepsSubtract one value from another. The order does not matter if you are dropping the sign, but you subtract the theoretical value from the experimental value if you are keeping negative signs. This value is your 'error'. continue reading below our video 4 Tips for Improving Test Performance Divide the error by the exact or ideal value (i.e., not your experimental or measured value). This will give you a decimal number. Convert the decimal number into a percentage by multiplying it by 100. Add a percent or % symbol to report your percent error value.Percent Error Example Cal

Accuracy describes the deviation between https://www.quora.com/The-maximum-error-in-the-measurement-of-mass-and-density-of-the-cube-are-3-and-9-respectively-What-will-be-the-maximum-error-in-the-measurement-of-length the average of the measurements and the minimum and maximum measurement. A small deviation indicates a more accurate measurement. Precision describes how closely the measurements correspond to the accepted value. It is possible to have accurate percent error measurements that are imprecise if the deviation between the measurements is small but the measurements differ significantly from the accepted value. Density is a measure of the mass of a substance per given volume. Things You'll Need Measured density Reference density Pencil Paper Measure the density of a substance by dividing the mass from the volume (density = mass/volume). Determine the density of liquids easily by measuring a volume of liquid in a density percentage error graduated cylinder and then finding the mass of the volume using a balance. For example, if 10 mL of liquid has a mass of 14 grams, then the density of the liquid is 1.4 grams per milliliter (14 g / 10 mL = 1.4 g/mL). Reference the accepted value for the density of the substance. Find published reference materials in a number of chemical reference books and chemical supply catalogs. Subtract the accepted density from the measured density. Divide the difference by the accepted value for the density and multiply the quotient by 100 [(measured density -- accepted density) ÷ accepted density x 100 = percent error]. Continuing the example, if the reference value for the density of the liquid in Step 1 is 1.2 g/mL, then the error is 16.7% [(1.4 g/mL -- 1.2 g/mL) ÷ 1.2 g/mL x 100 = 16.7%].

What will be the maximum error in the measurement of length?UpdateCancelAnswer Wiki1 Answer Ajay Sharma, Forget what we are told before we get too oldUpdated 113w agoDensity = Mass / (Length^3).or d = m/ l^3;Now see the magic of differentiation which i used in class 12th physics to calculate error in any equation. you just need to differentiate them wrt to any variable then using the info in the question rearrange terms to get the error.Please understand the concept and calculation only look big when you are explaining and not solving :Pd/dl of (density) = { length^3 * (d/dl of mass) - mass * 3(length^2) } / length^6where d/dl means diffrentiate w.r.t to length.so d/dl of (density) = { d/dl of mass / length^3 } - { mass ^ 3 / length ^4 }easy so far right, i mean normal differentiation.you can rewrite it as :(take dl from lhs to rhs)delta of (density) = { delta of (mass) / length^3 } - { 3 * mass * dl/ length^ 4}Now just divide both sides by density you will get(but why ?, because you need to get the error with respect to same item, for example d/dl of (density) means change in density wrt to length so now you need to take dl to rhs and then divide lhs by density so it becomes delta of (density) / density meaning change in density upon density which equals 9%)delta of (density) / density = { delta of (mass) / mass } - { 3 * delta of (length)/ length } lhs is given in question as 9% = 9/100left hand side of rhs is also given as 3% = 3/100so 3*delta of (length) / length = 6/100i.e change in mass w.r.t to mass is 2/100 (divide 6 by 3)Edited
