I would like to know the difference between the two. Thanks
In an experimental design there is manipulation of the independent variable (IV) under control of the experimenter and appropriate randomization to ensure that the effect of the IV on the dependent variable (DV) can be interpreted as being caused by the IV only. This could be random allocation to groups or random allocations to orders of conditions in a repeated measures design. If these requirements are not met or are relaxed but it follows the structure of an experiment then its a quasi-experiment in my view.

Hi,
Generally, quasi-experimental designs do not use random assignment, the approach used in experimental designs. That occurs most often because in a given situation that type of assignment is not possible.
Good luck with your project.
A quasi-experimental design is a non-randomized study design used to evaluate the effect of an intervention. The intervention can be a training program, a policy change or a medical treatment.
An experimental design is a randomized study design used to evaluate the effect of an intervention. In its simplest form, the participants will be randomly divided into 2 groups:
- A treatment group: where participants receive the new intervention which effect we want to study.
- A control or comparison group: where participants do not receive any intervention at all (or receive some standard intervention).
