Calculators Killed The Standard Statistical Table The Do Loop from blogs.sas.com Please enter the value of p above, and then press calculate z from p. Part of our free statistics package; What is a z table?
The table value for z is the value of the cumulative normal distribution at z.
Statext is a statistical program for personal use. If you don't see the answer you need, try the statistics glossary or check out stat trek's tutorial on the normal distribution.

Functions based on the normal distribution are easy to retrieve in code or excel, so we do not really need z tables anymore, in practice.
