(This is an example of a complete randomized design (CRD). DOE begins with determining the objectives of an experiment and selecting the process factors for the study. An Experimental Design is the laying out of a detailed experimental plan in advance of doing the experiment.

True experimental research design: True experimental research relies on statistical analysis to prove or disprove a hypothesis, making it the most accurate form of research. Of the types of experimental design, only true design can establish a cause-effect relationship within a group. Experimental research designs are also widely used in psychology, education, and the social sciences, and are considered the gold standard for evaluating causal hypotheses. Their logic as illustrated above is straightforward, though their actual execution can be quite challenging.

A good experimental design requires a strong understanding of the system you are studying. By first considering the variables and how they are related ( Step 1 ), you can make predictions that are specific and testable ( Step 2 ).

The simplest form of experimental research design in Statistics is the pre-experimental research design. In this method, a group or various groups are kept under observations, after some factors are recognised for the cause and effect.
