Linear Regression Calculator

Find the linear relationship between two variables by computing the slope, correlation coefficient, and R² from paired data points. Use it when analyzing trends in sales, scientific experiments, or any dataset where you want to predict one variable from another.

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.
