A laboratory experiment is where research is done in a highly controlled environment, where the level of control is very important. It is also to examine the validity of the hypotheses.

Each participant was told that there payment was for showing up and they could keep the payment no matter what happened after they arrived. On arrival the participant met the person leading the experiment and the subject who was in fact a stooge. The participant and the stooge then picked slips of paper to decide who would be the teacher and who would be
