Independent Samples t-Test Calculator

Compare the means of two independent groups using a Welch two-sample t-test.

 

Enter the numerical values for each group below. You can separate values using commas, spaces, or new lines.

 

Each group must include at least two numbers. After you click Run t-Test, the calculator will show the p-value, group means, standard deviations, mean difference, 95% confidence interval, t statistic, degrees of freedom, Cohen’s d, and a plain-English interpretation.

 

You will also get journal-style wording that you can use as a starting point for your report, thesis, or manuscript.
