Use our online statistical calculator to calculate the p-value of the Student's t-distribution. You just need to enter the t-value and degrees of freedom and specify the tail. In addition to the p-value, you can get and download the graph created with our graph generator.
T Distribution Graph Generator. Instructions: Make a t-distribution graph using the form below. Please type the number of degrees of freedom associated to the t-distribution, and provide details about the event you want to graph: Number of Degrees of Freedom (df df) Two-Tailed: ≤ t ≤. Left-Tailed: t ≤. Right-Tailed: t ≥.
T Distribution Calculator. The t distribution calculator makes it easy to compute the cumulative probability associated with a t score or with a sample mean. For help in using the calculator, read the Frequently-Asked Questions or review the Sample Problems.
The normal distribution is the limit of a t distribution when nu -> infinity. To the right we have a t distribution with nu degrees of freedom (blue), a normal distribution (black dashed), and a Cauchy distribution (red dashed).
The Student's t distribution is a continuous probability distribution that is often encountered in statistics (e.g., in hypothesis tests about the mean). It arises when a normal random variable is divided by a Chi-square or a Gamma random variable.
Use this t score calculator (same as t table calculator) to calculate t critical value by confidence level & degree of freedom for the Student’s t distribution.
