Student’s T Distribution PDF Calculator
Enter a t‑value and degrees of freedom to compute the PDF. The graph below shows the PDF curve.

How It Works
The Student’s T PDF is computed using:
$$ f(t;\nu)= \frac{\Gamma\Bigl(\frac{\nu+1}{2}\Bigr)}{\sqrt{\nu\pi}\,\Gamma\Bigl(\frac{\nu}{2}\Bigr)} \Bigl(1+\frac{t^2}{\nu}\Bigr)^{-\frac{\nu+1}{2}}. $$
The graph plots this PDF over a range of t‑values (from –5 to 5). The computed PDF at your input t‑value is highlighted.
