Type in up to ten values in cells labelled N1 to N10. The values can be in
any order, and cells can be left blank. Then press the "calculate" button
to generate the statistics. For 2 or more data points, all statistics can
be produced. you can change values individually or clear the whole set at
once with the "clear" button provided.
If a precision measure is given, the uncertainty in the average is the
of the precision measure and the standard deviation of the mean.
If a precision measure is given, the optimum number of measurements is
the number for which the
the precision measure and the standard deviation of the mean
should be equal
Note: The standard deviation calculated is the
deviation, not the
