The variability hypothesis hasn't found much support, and some results show the opposite, that females may have more variability. Overall, it seems that variability is basically equal between males and females. https://www.sciencedaily.com/releases/2005/03/050323124659.htm https://www.sciencedaily.com/releases/2005/03/050323124659.h... https://www.scientificamerican.com/article/anything-boys-can-do/ https://www.scientificamerican.com/article/anything-boys-can...
