# BOXCHART Statement: ANOM Procedure

#### Saving Summary Statistics for Groups

See ANMBXSUM in the SAS/QC Sample LibraryIn this example, the BOXCHART statement is used to create a data set containing group summary statistics that can be read later by the ANOM procedure (as in the preceding example). The following statements read measurements from the data set `LabelDeviations` and create a summary data set named `LabelSummary`:

```proc anom data=LabelDeviations;
boxchart Deviation*Position / outsummary=LabelSummary
nochart;
run;
```

The OUTSUMMARY= option names the output data set, and the NOCHART option suppresses the display of the chart, which would be identical to Figure 4.3.

Figure 4.6 contains a listing of `LabelSummary`.

There are nine variables in the data set `LabelSummary`.

• `Position` identifies the group.

• `DeviationL` contains the group minimums.

• `Deviation1` contains the first quartile for each group.

• `DeviationX` contains the group means.

• `DeviationM` contains the group medians.

• `Deviation3` contains the third quartile for each group.

• `DeviationH` contains the group maximums.

• `DeviationS` contains the group standard deviations.

• `DeviationN` contains the group sizes.

Note that the summary statistic variables are named by adding the suffix characters L, 1, X, M, 3, H, S, and N to the response `Deviation` specified in the BOXCHART statement. In other words, the variable naming convention for OUTSUMMARY= data sets is the same as that for SUMMARY= data sets.
