What is the Two Sample T-Test Calculator?

The Two Sample T-Test Calculator helps users compare two independent sets of numerical data to determine whether there is a significant difference between their means. By entering both datasets, the tool calculates the means, variances, sample sizes, and the resulting t-statistic using Welch’s t-test method. This makes it useful for students, researchers, and analysts who want a quick and accurate way to test differences between two groups without performing manual calculations, ensuring clearer understanding and better decision-making.

How to Use:

1. Enter Sample 1: Type the first group of numbers separated by commas (e.g., 10, 12, 15, 18).
2. Enter Sample 2: Type the second dataset in the same comma-separated format.
3. Click “Calculate”: The tool analyzes both samples and computes their means, variances, and the t-statistic.
4. Review Result: The output displays both sample summaries and the final t-value clearly.
