Excluding data points from an analysis

How do you exclude certain data points from an analysis?

-- If you don't want some values to be included in analyses or graphs, select them, and click the Exclude button in the Change section of the toolbar. Excluded values will appear in blue italics on the data table and will be 'invisible' to analyses and graphs. Select and click the button again to include them again.
