Normal Probability Calculator

Computes the integral and inverse integral for the Normal (Mu, Sigma) distribution. Plots of the probability density function and cumulative distribution function can also be requested.

Normal

Element Name Description
Inverse Creates the inverse of the integral; specify a desired p-value (e.g., significance level) to compute the critical z value for the Normal distribution.
Two-tailed test Select this option to specify a two-tailed test.
1 - Cumulative p Set this option to True to compute the (critical) variate value for the specified distribution based on a 1-cumulative-p value, or the 1-cumulative-p value based on a specified (critical) variate value.
Plots density function Plots the probability density function.
Plots distribution function Plots the distribution function.
Variate value z Specifies the (critical) z value for the computations.
p-value Specifies p-value for computations.
Mean Specifies value for the mean (Mu).
Standard deviation Specifies the value for the standard deviation (Sigma).
