Interactive Tools & Simulations
Hands-on tools to help you learn and practice data science concepts.
About These Tools
Learning by doing is the best way to master data science concepts. These interactive tools and simulations allow you to experiment with parameters, visualize concepts, and build intuition without writing any code.
🧮
Sample Size Calculator
Calculate the required sample size for your A/B tests based on baseline conversion rate, minimum detectable effect, and desired statistical power.

Visualization
🎯 Learning Tips
- Experiment freely: Adjust sliders and parameters to see how distributions and calculations change
- Connect to concepts: Refer back to the theory pages to understand the math behind what you're seeing
- Use in interviews: These tools help you estimate sample sizes and validate assumptions during case studies
- Build intuition: Understanding how parameters affect outcomes is key to practical data science
