Significance Testing - Color Comparisons with a Specific Column

From Q
Jump to: navigation, search

This rule uses the Column Comparisons to add color to cells which have a significant relationship to a particular column. This can be used, for example, to color any cells whose Column Comparisons letters indicate that the cell is significantly higher or lower than the NET. The rule will replace the column letters with colors when comparing against the target column, but will maintain the letters for other comparisons. This rule works within the spans of the table, so that if you wish to highlight comparisons with the NET or other column within each of the spans on your table, then this is done automatically.


In the following table, we have used this rule to highlight results which are significant compared with the results in the NET column. In the options we have specified orange for cells which are significantly low, and yellow for cells that are significantly high. Note that the Column Comparisons letters remain for comparisons that do not include the NET column.


Technical details

The Column Comparisons do not test with the NET column(s) by default, and in order to include the NET in the testing you must change the settings according to How to Include the Main NET Column in Column Comparisons.

How to apply this rule

For the first time in a project

  • Select the table(s)/chart(s) that you wish to apply the rule to.
  • Start typing the name of the Rule into the Search features and data box in the top right of the Q window.
  • Click on the Rule when it appears in the QScripts and Rules section of the search results.


  • Select Automate > Browse Online Library.
  • Choose this rule from the list.

Additional applications of the rule

  • Select a table or chart that has the rule and any table(s)/chart(s) that you wish to apply the rule to.
  • Click on the Rules tab (bottom-left of the table/chart).
  • Select the rule that you wish to apply.
  • Click on the Apply drop-down and choose your desired option.
  • Check New items to have it automatically applied to new items that you create. Use Edit > Project Options > Save as Template to create a new project template that automatically uses this rule.

Removing the rule

  • Select the table(s)/chart(s) that you wish to remove the rule from.

  • Press Apply next to the rule you wish to remove and choose the appropriate option.

How to modify the rule

  • Click on the Rules tab (bottom-left of the table/chart).
  • Select the rule that you wish to modify.
  • Click Edit Rule and make the desired changes. Alternatively, you can use the JavaScript below to make your own rule (see Customizing Rules).
