Other ways of calculating degrees of freedom for 2 samples The independent two-sample case has more subtleties, because there are different potential conventions, depending on whether the population variances are assumed to be equal or unequal. Even, there is a "conservative" estimate of the degree...
p-Value Calculator for an F-Test This calculator will tell you the probability value of an F-test, given the F-value, numerator degrees of freedom, and denominator degrees of freedom. Please enter the necessary parameter values, and then click 'Calculate'....
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'. ...
The formula for Welch’s t-test is: t=\frac{\bar{x}_{1}-\bar{x}_{2}}{\sqrt{\frac{s_{1}^{2}}{n_{1}}+\frac{s_{2}^{2}}{n_{2}}} Degrees of Freedom Formula To find the degrees of freedom when using Welch’s t-test, use the Satterthwaite formula: \...
