Mean, standard deviation and relative standard deviation are
calculated.

Step by step procedure

Select the data sets to be included in the statistics cal-
culation.

Open the statistics window (menu item "Data, Statistics").

Statistics calculations are carried out.

If you select more data sets, they will also be included in
the statistics calculation.
You can also select different data sets. Statistics calcula-
tion will be carried out as long as its window remains
open.

Close the statistics window if you are done with statistics.
If you keep the statistics window open, the database will

out.

tains this variable.
