Student's t Probability Calculator

Student t Probability calculator; computes the integrals and inverse integrals for the central Student t(df) distribution (with parameter df: degrees of freedom). Plots of probability density and distribution functions can also be requested.

Student t(df)

Element Name Description
Inverse Computes the inverse of the integral; specify a desired p-value (e.g., significance level) to compute the critical variate value for the respective 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.
Value of t Specifies the (critical) variate value for the computations.
p-value Specifies p-value for computations.
df Degrees of freedom.
