About this Tool
This program is designed to turn multiple comparison results from post-hoc analysis (like Tukey's HSD) into easily readable scientific Compact Letter Displays (CLD). It assigns letters to groups such that groups sharing the same letter are not significantly different.
How to use:
- Select the number of groups you analyzed.
- Choose input type: Mean/Error (Bar Graph) or Box Plot Stats (Box Plot) - (this is just for presentation).
- Enter the Group Names (Required) and data (Optional). Customize colors and patterns.
- Check the boxes for pairs that showed significant differences (p < 0.05) in your analysis.
* This application is for personal use only.

Compact Letter Display (CLD)
Interpretation:
Different letters in the same column indicate statistically significant difference (p<0.05).
