Follow 2 answers 2 Report Abuse Are you sure you want to delete this answer? Show that you did the calculation for both higher and lower speed and picked the higher one as the answer. I would probably put down the higher calculated error as my answer.

Percent Error Equation Step 5 Calculate relative error Calculate the relative error by dividing the absolute error by the measured value of the object. Use the range of speeds and this true speed to find a percentage error. https://www.reference.com/science/calculate-relative-error-3d05df913c8d5f7c A group of students have measured the time it takes for a cart to travel some distance along a level track.

What is the spread then in "speeds" using 190 and 194 seconds as the time traveled? Relative Standard Deviation Video should be smaller than 600mb/5 minutes Photo should be smaller than 5mb Video should be smaller than 600mb/5 minutesPhoto should be smaller than 5mb Related Questions Absolute error & relative The attempt at a solution This is were I get myself in a muddle I am not sure if I should add +/-4m to 800m to make it 804m and 796m Find the absolute error, relative error and relative percentage error.?

You simply multiply or divide the absolute error by the exact number just as you multiply or divide the central value; that is, the relative error stays the same when you Bad news for would-be speedsters on Italian highways. Actually, the conversion factor has more significant digits. A: The independent variable for the Drops on a Penny lab experiment is the type of solution used for the experiment.

Your cache administrator is webmaster. If the teacher doesn't agree, you will hopefully get most of the credit for having calculated both. The problem is that you will get a different answer if you use the upper speed to calculate percentage error than if you use the lower speed. I was taught that percentage error was abs( assumed answer - true value) / true value *100%.

Quick Tip: For example, if an object determined to be 1 meter long is measured to within an accuracy of plus or minus 1 millimeter, the absolute error 1 millimeter times
