Webpercent uncertainty. : where x is the mean as already discussed in Mean and σ is the uncertainty (the reason for this choice of symbol will be made clear later). Example. Consider two distance measurements each with an uncertainty of. The first is Dr. Toggerson’s height: The second measurement is the height of the library. WebSep 8, 2024 · In general, error is the difference between an accepted or theoretical value and an experimental value. Error = Experimental Value - Known Value Relative Error Formula Relative Error = Error / Known Value Percent Error Formula % Error = Relative Error x 100% Example Error Calculations
WebAug 28, 2024 · What is the uncertainty of a 25 mL pipette? Obtain a 25 mL volumetric pipette. The accuracy of these pipettes ranges from ± 0.01 mL to ± 0.06 mL depending on the “class” and size of pipette used. WebPercentage error = V observed – V true V true × 100% For example, if the observed value is 56.891 and the true value is 62.327, the percentage error is: 56.891 – 62.327 62.327 × 100% = 8.722% The equations above are based on the assumption that true values are known.
