Statistics
Linear Regression Slope Calculator
Calculate the slope of a least-squares linear regression line from summary statistics of paired x and y data. The slope tells you how much y changes per unit change in x — central to forecasting, regression analysis, and any task that quantifies a linear relationship between two variables.

Statistics
Standard Error Calculator
Compute the standard error of the mean (SEM) from the sample standard deviation and sample size, SEM = s/√n. Quantifies how precisely a sample mean estimates the underlying population mean — the foundation of confidence intervals, t-tests, and any inferential statistic.
