True Classical Experimental Design. Pre-test - post-test control group post-test only control group and a Solomon four group six-study design. Examples of true experimental designs are.
Research in which a causal relation between a manipulation of a variable an intervention and an assumed effect is investigated in the most valid way by comparing an experimental group with intervention with a control group without an intervention whereby the experimental and control group are made statistically comparable with. As a result any difference between the experimental and the control groups must have been due to the action of the experimental. The basic components of a true experiment include a pretest posttest control group and experimental group.
True experimental designs are used in various scientific experiments including drug trials where participants all have the same disease or illness but a portion of participants receive the treatment and a portion receive placebos.
