This calculator computes the t-value from a given correlation coefficient (r) and sample size (n). Use this tool to assess the statistical significance of the observed correlation. Remember, for important decisions, verify results with professional statistical software or consult a statistician.
t‑Value Calculator for Correlation Coefficients
Calculate the t‑statistic for a correlation coefficient using: $$ t = \frac{r\sqrt{n-2}}{\sqrt{1-r^2}}. $$
* Enter the correlation coefficient \( r \) (between -1 and 1) and sample size \( n \) (n > 2).
Step 1: Enter Data
e.g., 0.3 (must be between -1 and 1)
e.g., 30 (n must be greater than 2)
