A measurement result is the measured value displayed by a measuring instrument for a specific measured object, which is, however, subject to several influencing variables and uncertainties. It does not have to correspond to the true value.
Since measurements are subject to measurement uncertainties and measurement errors, measurement results correspond to the approximation of the actual measured quantity. Correctly, measurement results would have to be indicated with the measurement error and the measurement uncertainty.
To approximate the true value, measurements can be performed several times under the same measurement conditions and the mean value and standard deviation can be calculated from the measured values.
