This calculator will tell you the one-tailed and two-tailed probability values of a t-test, given the t-value and the degrees of freedom. Please enter the necessary parameter values, and then click 'Calculate'. Degrees of freedom:
Student t-Value Calculator This calculator will tell you the Student t-value for a given probability and degrees of freedom. Student t-values for both one-tailed (right-tail) and two-tailed probabilities will be returned.Please enter the necessary parameter values, and then click 'Calculate'....
Use the t critical value calculator to find the critical value of t, f, & chi-square if you don’t know how to find critical value.
Note:The t-distribution calculator only reports cumulative probabilities (e.g., the probability that a t score is less than or equal to a specified value.)

This calculator uses a two-samplettest, which compares two datasets to see if their means are statistically different. That is different from aone samplettest, which compares the mean of your sample to some proposed theoretical value. The most general formula for attest is composed of two means...
Enter either the p-value (represented by the blue area on the graph) or the test statistic (the coordinate along the horizontal axis) below to have the other value computed. Student's t-distribution Other distributions:Normal•Chi-square•F ...
A p value is computed based on the calculatedtratio and the numbers of degrees of freedom present (which equals sample size minus 1). The one samplettest calculator assumes it is a two-tailed one samplettest, meaning you are testing for a difference in either direction from the specified va...
