Subsecuentemente, los científicos realizan experimentos y/o observaciones que permiten recopilar datos cuyos resultados son utilizados para confirmar (o rechazar) la hipótesis nula. Por otra parte, es necesario resaltar que durante el proceso de experimentación se requiere de la utilización de controles positivos y negativos que permitirán corroborar si dichos experimentos fueron realizados correctamente.
