There are certain key components that must be included in every experiment. To eliminate lurking variables, subjects must be assigned randomly to different treatment groups. One of the groups must act as a control group, demonstrating what happens when the active treatment is not applied. Participants in the control group receive a placebo treatment that looks exactly like the active treatments but cannot influence the response variable.

In order to prove that the explanatory variable is causing a change in the response variable, it is necessary to isolate the explanatory variable. The explanatory variable is scent, and the response variable is the time it takes to complete the maze.

It emphasizes the significance of control groups and blinding to reduce bias, highlighting how expectations can affect outcomes.
