It is important to understand first the basic terminologies used in the experimental design. Experimental unit: For conducting an experiment, the experimental material is divided into smaller parts and each part is referred to as an experimental unit. The experimental unit is randomly assigned to treatment is the experimental unit.

Quasi-Experimental Designs Fall between observational (cohort) and experimental studies. There is an intervention, but often not completely planned ahead before conducting the research. Typically, random allocation is not involved. The experimenter doesn’t decide to whom the experimental treatment would be applied.
