Data & Stats Tooling

Power Analysis Tool

A fully interactive browser tool for exploring statistical power trade-offs across t-tests, ANOVA, and regression. It updates effect size assumptions, required sample size, and visual diagnostics in real time for study planning.

Live tool: all calculations run client-side with an interactive plotting surface.
Interactive Runtime
Open direct tool
Coverage Multi-test workflow

Supports two-sample and paired t-tests, one-way ANOVA, and regression with test-specific controls.

Outputs Power + required n

Computes estimated power, critical threshold, noncentrality proxy, and target sample-size recommendations.

Visualization 3 live plots

Distribution overlays, power curves, and simulated sample behavior make planning assumptions easier to audit.

Built With

JavaScript Plotly Interactive UI Statistical Modeling

Use Cases

Designed for experiment planning, study design discussions, and classroom demonstrations where users need immediate feedback on alpha, effect size, and n trade-offs.

Why It Matters

  • Brings common power-planning steps into one consistent UI
  • Reduces dependency on disconnected calculators and scripts
  • Makes assumptions transparent through live visual feedback
