Last week, we understood what experiments are (not). A robust experiment allows strong conclusions to be made. . How do we design robust experiments? . We . control. for variables which can upset or compromise our conclusions!. A very common way of research design. A good design to establish cause and effect relationships among variables. It is the type of research that. directly attempts to influence a particular variable. So, the basic experimental procedure in social science is:.
