This program calculates the t-value and significance probability for a “paired two-sample t-test” for beginners in statistics.
We will test the difference between Group A and Group B. The null hypothesis is “the mean of Group A equals the mean of Group B.”
Before performing the test, decide on the type of test (one-tailed or two-tailed), the alternative hypothesis, and the significance level.
Once you have decided, enter the mean, standard deviation, and degrees of freedom for “Group A – Group B,” then click “Calculate.”

| t = | p = |
| (Rejectable boundary point t0 = | ） |
*If the test result displays as 99, it indicates an error because the null hypothesis does not correspond to the one-tailed or two-tailed test.
