Experimental design provides the greatest amount of control possible to examine the causality. There are three main characteristics: 1) Controlled manipulation of at least one of the treatments, 2) Exposure of treatment to some of the subjects but no exposure to the remaining subjects.3) Random assignments to the control (no treatment) and the experimental group. Examples of experimental groups would be any of the drug treatment research, currently would be the use of Tylenol and ibuprofen simultaneously gives the same amount of pain relief as opioid medications without the mind altering effects.

Non experimental design focuses on examining variables as the are naturally occurring in an environment without any implementation of a treatment. I would think of this like studying the growth charts of babies in different cultures and different countries to see how the environment that they live in effects the growth curve. Non experimental design offers no control over the outcomes.

Quasi-experimental appraoch is like the middle man where there is less controlled conditions.
