Tresset [83]

Answer:

For instance, various independent variables are strictly altered and observed while controls are kept constant - this ensures validity and can indicate if the experiment was influenced by external factors. Here, the factor being changed or tested is the temperature, and the factor being observed is the resulting biological sex of the organism.
