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...
As long as you’re using statistical software, such asthis two-sample t test calculator, it’s just as easy to calculate a test statistic whether or not you assume that the variances of your two samples are the same. If you’re doing it by hand, however, the calculations get more comp...
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:

This calculator will tell you the observed power for a one-tailed or two-tailed t-test study, given the observed probability level, the observed effect size, and the total sample size. Please enter the necessary parameter values, and then click 'Calculate'. ...
The calculator assumes that all samples have the same Skewness and Kurtosis.Monte Carlo SimulationThe data for minimum sample size formulas are derived from extensive Monte Carlo simulations for n = 2 to 2000. Observed alpha values were determined empirically from the p-values of 100,000 replicate...

To find the probability associated with a t statistic, use a t-distribution table (found in the appendix of most introductory statistics texts), a graphing calculator, an online t-distribution calculator, like Stat Trek's T Distribution Calculator....

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...
