Power and Sample Size Calculator

Purpose

Provides statistical power analysis and sample size determination capabilities for experimental design.

Capabilities

  • Power analysis for common tests (t-test, ANOVA, chi-square)
  • Effect size calculation
  • Sample size estimation
  • Simulation-based power analysis
  • Multi-level model power analysis
  • Sequential analysis design

Usage Guidelines

  1. Effect Size: Specify meaningful effect sizes
  2. Power Target: Set appropriate power levels (typically 0.80)
  3. Type I Error: Control alpha appropriately
  4. Simulation: Use simulation for complex designs

Tools/Libraries

  • G*Power
  • pwr (R)
  • statsmodels
