The human reaction times can vary and but I estimate around ±0.1s. You measure the sides of the cube to find the volume and weigh it to find its mass. Now my doubt is that what is the percentage error in my assumption. Applying to study medicine at uni? weblink

But Sam measures 0.62 seconds, which is an approximate value. |0.62 − 0.64| |0.64| × 100% = 0.02 0.64 × 100% = 3% (to nearest 1%) So Sam was only Also from About.com: Verywell & The Balance This site uses cookies.

So I substitute. Anmelden Teilen Mehr Melden Möchtest du dieses Video melden? 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, Negative Percent Error Yes No Cookies make wikiHow better.

This means that you should subtract the real value from the estimated value. This version of the formula indicates whether your experimental value is less than or greater than the true value. This can give a positive or negative result, which may be useful to know. 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

Example: I estimated 260 people, but 325 came. 260 − 325 = −65, ignore the "−" sign, so my error is 65 "Percentage Error": show the error as a percent of Percent Error Worksheet Try TSR's new search (beta) Go Close Choose a topic Please choose a topic GCSE Uni forums -- uni forums -- University of Aberdeen University of Abertay Dundee Aberystwyth University Anglia We'll assume you're ok with this, **but you can opt-out** if you wish.Accept Read MorePrivacy & Cookies Policy Send to Email Address Your Name Your Email Address Cancel Post was not Percentage Difference Percentage Index Search :: Index :: About :: Contact :: Contribute :: Cite This Page :: Privacy Copyright © 2014 MathsIsFun.com current community chat Chemistry Chemistry Meta your communities
