Calculate Percent ErrorLast modified: January 28th, 2016 by Todd HelmenstineShare this:GoogleFacebookPinterestTwitterEmailPrintRelated This entry was posted in Measurement and tagged example problems, experiments, homework help, measurement, percent error on May 16, 2014 Hochgeladen am 01.08.2010To see all my Chemistry videos, check outhttp://socratic.org/chemistryHow to calculate error and percent error. Typically, you hope that your measurements are all pretty close together. 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

Three (3) standard deviations (the red, green and blue areas) account for about 99 percent of the data points.

We, however, don't have a stats calculator (well, we do, but we're pretending!), so we have to do it the hard way. 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, Du kannst diese Einstellung unten Ã¤ndern. Thank you,,for signing up!

Since the experimental value is smaller than the accepted value it should be a negative error. One standard deviation (sometimes expressed as "one sigma") away from the mean in either direction on the horizontal axis (the red area on the above graph) accounts for somewhere around 68 SpÃ¤ter erinnern Jetzt lesen Datenschutzhinweis fÃ¼r YouTube, ein Google-Unternehmen Navigation Ã¼berspringen DEHochladenAnmeldenSuchen Wird geladen...
