Frequently Asked Questions
A t-test is a statistical test used to compare the means of two groups to determine if they are significantly different from each other.
The p-value indicates the probability of observing the data given that the null hypothesis (no difference) is true. A low p-value (< alpha) suggests rejecting the null hypothesis.
This calculator assumes independent samples, equal variances, and normally distributed data. Use Welch's t-test if variances are unequal.
