Statistical design examples#

This notebooks shows various examples of statistical design calculations, which involve the trade-offs between four parameters of a scientific study:

  • Type I error rate \(\alpha\)

  • Type II error rate \(\beta\)

  • The unknown effect size we want to detect \(\Delta\)

  • Sample size \(n\)

One-sample test#

  • z-approx

Two-sample tests#

  • z-approx formula
