+### Usage
+
+```c
+#include "stdlib/stats/base/dists/hypergeometric/mode.h"
+```
+
+#### stdlib_base_dists_hypergeometric_mode( N, K, n )
+
+Returns the mode of a hypergeometric distribution.
+
+```c
+double out = stdlib_base_dists_hypergeometric_mode( 16.0, 11.0, 4.0 );
+// returns 3.0
+```
+
+The function accepts the following arguments:
+
+-   **N**: `[in] double` population size.
+-   **K**: `[in] double` subpopulation size.
+-   **n**: `[in] double` number of draws.
+
+```c
+double stdlib_base_dists_hypergeometric_mode( const double N, const double K, const double n );
