Both calculators run independently — change the inputs on either side to compare results.

Hypothesis Test Calculator

Run a one-sample z-test or t-test to determine whether a sample mean significantly differs from a hypothesized population mean. Essential for quality control, clinical trials, and academic research.

Probability

Hypothesis Testing Calculator

Run a one-sample t-test to decide whether a sample mean differs significantly from a hypothesised population mean. Returns 1 (reject the null hypothesis) or 0 (fail to reject) at your chosen confidence level using the one-sample t-statistic and a critical-value lookup.
