Statistical analysis of measurements subject to random errors

Weball other errors have been included in the measured uncertainty range and the accepted value still lies outwith this range then: (a) we must say that there has been some systematic error WebNov 8, 2016 · Random Errors. Random errors are ones that are easier to deal with because they cause the measurements to fluctuate around the true value. If we are trying to measure some parameter X, greater random errors cause a greater dispersion of values, but the mean of X still represents the true value for that instrument.
