Statistics
Correlation Coefficient Calculator
Compute the Pearson correlation coefficient r and coefficient of determination R² from summary statistics of paired data. Use it to measure the linear relationship between two variables in research or data analysis.

Statistics
Coefficient of Variation Calculator
Compute the coefficient of variation (CV), a dimensionless measure of relative variability defined as the standard deviation divided by the mean, expressed as a percentage. Used to compare variability across datasets with different units, magnitudes, or context — investment risk, biological variability, measurement precision.
