Frequently Asked Questions
A Student's t-test is a statistical test used to compare the means of two groups to determine if there is a significant difference between them.
This calculator assumes that the two samples are independent, the data are approximately normally distributed, and the variances are equal (pooled variance).
The p-value is computed using the t-distribution with degrees of freedom equal to n1+n2-2. It is two-tailed, meaning it tests for difference in either direction.
