Design Command Line Tool for Statistical Experiments Module

We need to design the user interface for a module that assists with statistical experiments. The UI will be created using Balsamic for visualization purposes. The module itself will be a Python command-line tool that utilizes argparse for parsing command-line arguments.

Key Features:
- Intuitive command-line interface for easy interaction
- Clear and concise display of statistical experiment options
- Error handling for invalid inputs
- Help documentation for users to understand available commands

Please provide mockups and suggestions for the UI design in Balsamic. Your input will be crucial in creating a user-friendly and efficient tool for statistical experiments.
