P.M. Wanek, Richard E. Whipple, T.E. Fickies, Patrick M. Grant · Analytical Chemistry · 1982
The problems arising with data sets consisting of tightly bunched arrays and severe calculation round-off errors when electronic calculators are used to calculate standard deviation of data are discussed. A simple remedy to the problem is set forth briefly.
