Significance Testing in Tables - Color Significant Cells

From Q
Jump to navigation Jump to search

This rule changes the color of the cells in the table when the results in the cells are found to be significant. This is equivalent to Q's standard Cell Comparisons, indicated by the arrows and font colors, except that the whole cell will be colored rather than just the fonts.



Technical details

The results shown as significant will match the results shown by Q's standard Cell Comparisons testing, which is indicated by arrows and font colors. To remove the arrows or font colors (or both), make a selection from the Show significance menu above the table.
