Its various computational components are programmed entirely in JavaScript   All calculations are performed within your browser. There is no transmission of data back and forth between your computer and the server.cropped-cropped-toolkit-24157707-copy.jpg

Calculators for Statistical Table Entries include:

  • z to P
  • chi-square to P
  • t to P
  • r to P
  • F to P
