This article describes how to show only one level of statistical significance when doing column comparisons.

By default, when using column comparisons, Q uses both upper and lowercase letters to show statistical significance, with uppercase (e.g., `A B C`) to show results significant at the 0.001 level (99.9% level of confidence), and lowercase (e.g., `a b c`) to show significance at the 0.05 level (95%).

## Requirements

- A table you want to analyze using column comparisons

## Method

- Right-click on the table and go to
**Table Options >****Statistical Assumptions**. - In the
**Significance levels and appearance**grid, copy the one uppercase**Column letters**fields (i.e.,`A,B,C,...,`) and paste it over the top of each of the lowercase fields (i.e.,`a,b,c,...,`). - Press
**OK**.
