Comparing Columns Across Spans

From Q
Jump to navigation Jump to search

The default statistical testing using in Q for Column Comparisons only compare columns within a span. There are a number of strategies for overcoming this limitation:

  1. Over-ride the significance tests. Note that this applies to whichever tables are selected at the time, and any tables copied and modified thereafter.
  2. Where the focus is on comparing dates within a Banner, see the Significance testing section on Banners.
  3. Remove the spans from the table and instead add text to the column headers to denote which columns are related.
  4. Create a Custom Rule.
