Explanation: In some cases, the measurement may be so difficult that a 10 % error or even higher may be acceptable. In other cases, a 1 % error may be too high. Most high school and introductory university instructors will accept a 5 % error. But this is only a guideline. At higher levels of study, the instructors usually demand higher accuracy.

Is a term used to describe the proportion of audit adjustments found in a sample of transactions. E.g: "Error": Subtract Approximate value from Exact value. Ignore any …minus sign. Example: I estimated 260 people, but 325 came. 260 - 325 = -65, ignore the "-" sign, so my error is 65 (MORE) 1 person found this useful What would you like to do? Flag Blue 518,948 Contributions Answered In Science Can percent error be negative? Sometimes you will take the absolute value of the percent error because your estimated number could be less than the theoretical, meaning the calculation is negative. But an a…bsolute value is always positive. A percent error can be left as a negative though, and this would be perfectly acceptable (or even preferred) depending on what you're doing. Answer:In the sciences, a negative percent error indicates a

A: Quick Answer Percent error can be a negative number. In some cases a positive percent error is typical, but http://www.mathsisfun.com/data/percentage-difference-vs-error.html applications such as chemistry frequently involve negative percent errors.

Credit: Fuse N/A Getty Images Full Answer Percent error is useful in experiments and calculations involving known values; it provides a means of ascertaining the accuracy of calculations. Determining percent error is simple; subtracting the actual value from the experimental value, dividing by the actual value and multiplying the entire what is a product by 100 yields percent error. A percent error of zero indicates that an experimental value is exactly the same as the actual, accepted value. Percent errors are often positive with the difference between experimental and actual results being an absolute value. This is the case when it is important to determine error, but the direction of the error makes no difference. In some situations, however, the direction of the deviation is important. Chemistry, and some other sciences, maintain negative percent error values. For instance, a given reaction between two substances may have a previously published final yield. It is important for any scientists performing this reaction to report on its accuracy. It is also important to know the direction of the error. A positive percent error means that the reaction had a higher-than-expected yield while a negative error indicates a lower yield.

a percentage of one (or both) values Use Percentage Change when comparing an Old Value to a New Value Use Percentage Error when comparing an Approximate Value to an Exact Value Use Percentage Difference when both values mean the same kind of thing (one value is not obviously older or better than the other). (Refer to those links for more details) How to Calculate Step 1: Subtract one value from the other Step 2: Then divide by ... what? Percentage Change: Divide by the Old Value Percentage Error: Divide by the Exact Value Percentage Difference: Divide by the Average of The Two Values Step 3: Is the answer negative? Percentage Change: a positive value is an increase, a negative value is a decrease. Percentage Error: ignore a minus sign (just leave it off), unless you want to know if the error is under or over the exact value Percentage Difference: ignore a minus sign, because neither value is more important, so being "above" or "below" does not make sense. Step 4: Convert this into a percentage (multiply by 100 and add a % sign) The Formulas (Note: the "|" symbols mean absolute value, so negatives become positive.) Percent Change = New Value - Old Value × 100% |Old Value| Example: There were 200 customers yesterday, and 240 today: 240 - 200 × 100% = (40/200) × 100% = 20% |200| A 20% increase. Percent Error = |Approximate Value - Exact Value| × 100% |Exact Value| Example: I thought 70 people would turn up to the concert, but in fact 80 did! |70 - 80| × 100% = (10/80) × 100% = 12.5% |80| I was in error by 12.5% (Without using the absolute value, the error is -12.5%, meaning I under-estimated the value) Percentage Difference = | First Value - Second Value | × 100% (First Value + Second Value)/2 Example: "Best Shoes" gets 200 customers, and "Cheap Shoes" gets 240 customers: | 240 - 200 | × 100% = |40/220| × 100% = 18.18...% (200+240)/2 Percentage Difference Percentage Error Percentage Change Percentage Index Search :: Index :: About :: Contact :: Contribute :: Cite This Page :: Privacy Copyright © 2014 MathsIsFun.com
