Sample Size Calculator
Determine optimal sample sizes for your experiments with statistical rigour. Covers A/B tests, surveys, and observational studies with sensitivity analysis and plain-English guidance on parameter selection.

The Lab Hands-on Exploration
The Lab section represents the most interactive and experimental portion of DataScienceDNA, transforming passive learning into active exploration. Rather than simply reading about data science concepts, visitors can manipulate parameters, test hypotheses, and see results unfold in real-time.
This hands-on approach reduces the barrier between understanding theory and applying practice, whilst demonstrating technical capabilities through production-ready applications that solve real problems.

Production-ready applications that solve real problems — from experimental design to model evaluation and business planning.
ML Model Comparison
Compare algorithm performance side-by-side and understand trade-offs between different approaches. Train multiple models simultaneously on the same dataset, with animated decision boundaries and comprehensive metric dashboards.
ROI Calculator
Calculate data science project return on investment with comprehensive cost modelling. Structures ROI around revenue enhancement, cost reduction, and risk mitigation — including Monte Carlo sensitivity analysis.
The Platform
Experimental. Interactive. Hands-on.
Three modes of active engagement with modern data science — each reducing the barrier between understanding and doing.
Experimental
Manipulate parameters directly and see results unfold in real-time. Adjust sliders, inject outliers, tune hyperparameters, and observe how models respond — building intuition that passive reading cannot provide. Every demo exposes the internal mechanics rather than hiding them.
Interactive
Zero-setup sandboxes, visual algorithm explorers, and guided challenge problems meet learners at every level. Beginners discover fundamental concepts through visual interfaces; advanced users push boundaries with cutting-edge techniques and Kaggle-style competitions.
Hands-on
Production-ready tools that solve real daily problems — sample size planning, A/B test evaluation, feature importance calculation, ROI estimation. Each utility combines rigorous statistical foundations with accessible interfaces that don't require memorising obscure formulas.
