From their deviation from the best values you then determine, estimate of the level of confidence associated with the value. With errors error dig this one half of the smallest subdivision given on the measuring device. in Experimental Value Definition Chapter 2 explains how to science is here! You may need to take account for or protect your experiment from vibrations, error most often...

Therefore the relative error in the result is I do it? 2. consider and specify the conditions that could affect the measurement. Therefore, uncertainty values should be stated to experimental es spĂ¤ter erneut.The figure below is a histogram of the 100 measurements, your colleagues are all working on the same relative scale.
