Observed signal levels: none DUT7 115.3191 115.2602 115.3157 115.2532 115.3154 averages 115.3167 115.2567 Standard deviations in individual measurements 0.0020 0.0050 Very few points, use the average standard deviation which is 0.0038 (rms) Standard deviation of averages 0.0022 0.0027 Standard deviation of average difference 0.0035 IL = 115.3167 - 115.2567 = 0.0600 dB Standard deviation 0.0035 dB Error limits (3 sigma) +/- 0.0105 dB Errors are estimated from far too few data points so the error estimation for this particular measurement is very uncertain. There are many measurements in this series so the statistics of all the errors estimates will give a good idea about errors. |
