Any change in one or more of the elements of the system will cause a change in the character of the systematic error. Many thanks for the explanation as always!I dont know if this is related question, but is the probable error the same as error bars plotted on a graph?My second question would be in regards to the Standard Deviation, the example above shows a normal distribution.
I don't think it is the probably error, probably just one standard deviation. The moving range is the range between consecutive points. It is necessary to

We could also compute the relative error with regard to probable error, found by dividing the whole equation by Q, as follows: r/Q= ((Q/q1)2(r12/Q2)) + (Q/q2)2r22/Q2) +. About 68% of the values fall between -1 and +1 standard deviation from the average, About 95% of the values fall between -2 and +2 standard deviations from the average, About 99.97% of the value fall between -3 and +3 standard deviations from the average. If the measurement increment is too large, you will need to decrease the measurement increment so it is within the range. The true value is between 8.009924 and 8.006076 GHz.
