Key features of lab experiments

  • Control - a lab experiment is a controlled experiment. The lab is an artificial environment where the researcher can control different variables. The researcher puts subjects into an experimental group and a control group. The experimental group are exposed to a variable that the researcher believes may have a particular effect. The control group aren’t exposed to it

  • Cause and effect - If we discover a change in the experimental group but not the control group, we can discover a cause-and-effect relationship

  • While lab experiments are the basic research method in most natural sciences, they are rarely used in sociology due to practical, ethical and theoretical issues
