Calculation path
Test a sample Pearson correlation against zero with its associated t statistic. The page evaluates the displayed equation from your supplied values and presents both symbolic and substituted KaTeX working so the arithmetic can be checked.
Calculation path
t=r sqrt[(n-2)/(1-r^2)]
What you receive
What you receive
- Correlation t statistic from the stated equation
- A symbolic formula plus substituted working with your values
- Visible assumptions, field guidance, and an authoritative learning reference

Choose the maximum decimal places shown. This does not increase source accuracy.
Pairs are independent, approximately bivariate normal, and the relationship is linear without dominant outliers.
Use internally consistent units and retain extra precision when carrying the result into another calculation.
