Manish Arora Posted November 21, 2012 Report Share Posted November 21, 2012 I have a physics lab due next week, does anyone no how to calculate the error percentage of the following readings?0.09616677875 N0.2645755989 N1.978381515 N0.07387299429 N0.1962737545 N Reply Link to post Share on other sites More sharing options...
Avtej Sethi Posted November 21, 2012 Report Share Posted November 21, 2012 ya i do. but what are the variables involved. what instrument did you use. what is its least count. and error for all the readings also counts. Reply Link to post Share on other sites More sharing options...
macrofire Posted November 22, 2012 Report Share Posted November 22, 2012 I have no idea what you're talking about....but when I see that data, I'm thinking of an expected value and its variance. Perhaps it's similar to the true value of something and the error. Reply Link to post Share on other sites More sharing options...
Dr. Jenkins Posted November 22, 2012 Report Share Posted November 22, 2012 Yes to get the error we just need the precision of the force meter used, or the measurements and previous calculations done Reply Link to post Share on other sites More sharing options...
ChocolateDrop Posted November 22, 2012 Report Share Posted November 22, 2012 (edited) <------- Use this format and plug in the data.. What kind of data is it? You have to find out the literature values i.e the value you woould expect. Eg if you were doing an enthalpy of combustion of ethanol. Your experiment gives you certain values, this is the 'measured' value, then you do a little research and find the 'actual' value also known as the literature value and plug them in the equation.
