CrystalsPhysics ProblemsMy Amazon StoreShop Calculate Percent Error 3 Replies Percent calculating percentage error between two values error, sometimes referred to as percentage error, is an expression of the difference between a calculating percentage error of equipment measured value and the known or accepted value. It is often used in science to report the difference between experimental values and expected values.The

formula for calculating percent error is:Note: occasionally, it is useful to know if the error is positive or negative. If you need to know positive or negative error, this is done by dropping the absolute value brackets in the formula. In most cases, absolute error is fine. For example,, in experiments involving yields in

chemical reactions, it is unlikely you will obtain more product than theoretically possible.Steps to calculate the percent error:Subtract the accepted value from the experimental value.Take the absolute value of step 1Divide that answer by the accepted value.Multiply that answer by 100 and add the % symbol to express the answer as a percentage.Now let's try an example problem.You are given a cube of pure copper. You measure the sides of the cube to find the volume and weigh it to find its mass. When you calculate the density using your measurements, you get 8.78 grams/cm3. Copper's accepted density is 8.96 g/cm3. What is your percent error?Solution: experimental value = 8.78 g/cm3 accepted value = 8.96 g/cm3Step 1: Subtract the accepted value from the experimental value.8.96 g/cm3 - 8.78 g/cm3 = -0.18 g/cm3Step 2: Take the absolute value of step 1|-0.18 g/cm3| = 0.18 g/cm3Step 3: Divide that answer by t

The formula is given by: The experimental value is your calculated value, and the theoretical value is your known value. A percentage very close to zero means you are very close to your targeted value, which is good. It is always necessary to understand the cause of the error, such as whether it is due to the imprecision of your equipment, your own estimations, or a mistake in your experiment.Example: The 17th century Danish astronomer, Ole Rømer, observed that the periods of the satellites of Jupiter would appear to fluctuate depending on the distance of Jupiter from Earth. The further away Jupiter was, the longer the satellites would take to appear from behind the planet. In 1676, he determined that this phenomenon w
