T-Test Calculator Compare the means of two samples using a single-sample or two-sample t-test below. Results: Two-tailed P: Left-tailed P: Right-tailed P: Test Statistic (t): Degrees of Freedom (df): Learn how we calculated thisbelow...
we explain each type of t-test using practical examples and teach how to calculate the t-test value. You can also use the downloadable Excel template and the t-test calculator for better understanding. You may also look at the following articles to learn more – ...
The test statistic is {eq}\chi^{2}=0.066+1.066+1.066+0.066=2.264 {/eq}. For a Chi-Square distribution with 4-1=3 degrees of freedom, we compute the p-value using an online calculator (such as https://www.statology.org/chi-square-p-value-calculator/)...
