z to P Calculator
For any given value of z, this page will calculate
To proceed, simply enter the value of z in the designated cell and click "Calculate." Note that the programming for this page is able to perform meaningful probability calculations only for cases where |z|<5.
- the respective one-
tailed probabilities of z and +z;
- the two-
tailed probability of±z;
- and the proportion of the normal distribution falling between z and +z.
Probabilities P one-tailed for z one-tailed for +z two-tailed for ±z area between ±z
