The second image is a continuation of the first one.

Compute average of differences. average 0.0503 Standard deviation of individual difference 0.023 Standard deviation of average difference, IL, 0.0012 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. |
