10.4 GETTING STATISTICAL INFORMATION ABOUT SAMPLES
After creating a graph as described above, click on the STATS button to display the Stat Sheet.
This tabbed dialog displays statistical information for each of the variables on the graph. To
display a statistic, click on the corresponding Plot check box. Statistics can be selected to be
plotted on the graph for Sample 1 only, but statistical information will be displayed on the Stat
Sheet for both samples.
To select statistical lines to be plotted on the graph, click on the Plot checkbox next to the
statistics you want to show then click the OK button.
The default values for the four lines displayed by the Standard Deviation (
σσσσ
) section are the
Mean

and the Mean

σ
. The 2 and 3 can be changed in the two fields above the resulting
values.
The Precision section multiplies the Mean by standard Shewhart factors. These factors may also
be changed if needed.
The values shown in the Quality Control section are values that have been entered in the QC
fields of the Sample Setup.
