Hello Course Hero Tutors I Have A Question I Am Doing A Powerpoint Presentation

Hello Course Hero tutors

I have a question, I am doing a powerpoint presentation for PS 504 on the Stanford Prison Experiment by Philip Zimbardo. I already have 2 slides, and going good, but I cannot find what Method of Study was was used for this experiment. Example: Single-Subject Design, Matched Design etc. Can you help ? I have researched websites and cannot find method of study.

Thank You,

Amanda
