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
Mean Calculator
Compute the arithmetic mean (average) of any comma-separated list of numbers — the most common measure of central tendency in statistics. The result is the sum divided by the count, equivalent to balancing a see-saw of the data points.
