2、it changes one or more process variables to observe the response variable changes, it is a procedure for obtain the research data, and gain yield valid and objective conclusion (Winer, 1971).Experimental design is a research design that eliminates all factors that influence outcome except for the ca

3、use being studied (independent variable), all other factors are controlled by randomization, investigator-controlled manipulation of the independent variable, and control of the study situation by the investigator, including the use of control groups (Medical dictionary). 2 Significance of experimen

5、s the power to be the most rigid type of research (most precise/ strict). Experimental design is the most rigorous of all research designs. 2.2 Be used to exploring the effectiveness of an intervention or treatment, how effective the intervention is? In other words, the experimental design gives evi

7、tion in details of the experiment makes the desired statistical analyses possible, and almost always improves the usefulness of the results (Barker, 2016). 2.5 Experimental design is the process of planning a study to meet specified objectives, it is very important to ensure that the right type of d
