The measurement increment is 0.1. Obviously, it means that 50% of the time the result will within one PE of the average - and 50% of the time it will be outside 1 PE. 1. The frequency and the probable error are therefore 79.477 .07163 kHz. This is shown in Figure 4. of base l = Nominal length of measuring Does the same principle apply for a non normal distribution?Many thanks. It is used to gauge how effective an improvement or change initiative is. What is Probable Error? Very often, in the test and measurement industry, a measurement is made by instrumentation, which is often subject to errors. mega888 1.
