We need to design the user interface for a new module that will assist users with conducting statistical experiments. The UI will be created in Balsamic for wireframing purposes and implemented in Streamlit for the final interface.

Requirements:

• The UI should be user-friendly and intuitive for users to navigate through different statistical tools and features.
• Include options for users to input data, select statistical tests, and visualize results.
• Ensure the design is clean, modern, and visually appealing to enhance user experience.

Tasks:

1. Create wireframes in Balsamic for the different screens and functionalities of the module.
2. Incorporate feedback from stakeholders to refine the UI design.
3. Implement the final UI design in Streamlit for seamless integration with the 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.

I would like to request the development of a sample size calculator for experiments. This tool should help researchers and scientists determine the appropriate sample size needed for their experiments based on factors such as desired confidence level, margin of error, and population size. Having a reliable sample size calculator will greatly benefit those conducting experiments and ensure that their results are statistically significant. Thank you for considering this request.
