## Main Question or Discussion Point

I have the following sample of measurements "V" and each has error "E" incorporated in the measurement. If I want to take mean of the sample how should I proceed. I figure that I can compute "sigma" by taking square root of the (sum of square of deviations from the mean divided by the number of sample-1). but that sigma will not incorporate the "E" errors inherent in the "V"

V E

I can compute mean and stddev suing Matlab, but how do I incorporate "E" in the computation.

thanks,
