The T-Test Calculator performs hypothesis testing for means using Student's t-distribution. It supports one-sample t-tests, two-sample independent t-tests (Welch's method), and paired t-tests with step-by-step solutions.
Enter your sample data or summary statistics, choose your test type and significance level, and get instant results including the t-statistic, degrees of freedom, p-value, and a clear conclusion about whether to reject the null hypothesis.
