This article describes how to go from a crosstab...
...to a crosstab showing Row Comparisons based on Column %:
Requirements
Please note these steps require a Displayr license.
- A table that displays Column % and has a Nominal or Nominal-Multi variable set in the Rows.
- Sample sizes MUST be the same across the rows within each column or results will be wrong.
Method
- Select your table.
- From the object inspector, go to Data > Rules.
- To apply the rule, select the Plus (+) > Significance testing in Tables > Row Comparisons using Column %.
- Set the Lowercase confidence level. By default, this is 0.1 (90%).
- Set the Uppercase confidence level. By default, this is 0.05 (95%).
- Press OK.
- Select Column Comparisons on the object inspector under Data > Statistics > Cells.
Please note the following:
- Comparisons are performed using the Chi-Square Test for Compatibility of K Counts for each pair of rows within each column of the table.
- Other than design effects and weights, the specified settings under Appearance > Appearance > Significance > Advanced are not taken into account by this test. That is, it will not take into account multiple comparison corrections, specified significance levels, or any other test parameters.
- NET rows are automatically excluded from the testing.
