+### Usage
+
+```c
+#include "stdlib/stats/base/dists/kumaraswamy/stdev.h"
+```
+
+#### stdlib_base_dists_kumaraswamy_stdev( a, b )
+
+Returns the standard deviation of a Kumaraswamy's double bounded distribution.
+
+```c
+double v = stdlib_base_dists_kumaraswamy_stdev( 0.5, 1.0 );
+// returns ~0.298
+```
+
+The function accepts the following arguments:
+
+-   **a**: `[in] double` first shape parameter.
+-   **b**: `[in] double` second shape parameter.
+
+```c
+double stdlib_base_dists_kumaraswamy_stdev( const double a, const double b );
