Experimental research provides the most powerful design for testing causal hypotheses because it allows us to confidently establish the first three criteria for causalityassociation time order and nonspuriousnessTrue experimentshave at least three features that help us meet these criteria.
The classical experimental design.
Daniels proposed research was set up along what is known as the classical experimental design. Dec 03 2019 Experimental design means creating a set of procedures to test a hypothesis. According to current methodology this design is composed of control and experimental groups with each group being subject to a before-and-after test. 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.
