Statistics
One-Sample T-Test Calculator
Compute the one-sample t-statistic to test whether your sample mean differs significantly from a known or hypothesised population mean. The first inferential test most students learn — used in survey analysis, quality control, and any single-group comparison against a benchmark.

Statistics
Hypothesis Test Calculator
Compute a z-score or t-statistic to determine whether your sample mean differs significantly from a hypothesized population mean. Use it for quality control checks, clinical trials, and any experiment where you need to accept or reject a null hypothesis.
