Reflect On The Different Experimental Designs

Introduction In researches, the researcher decides and selects whether s/he is willing to use one or more than one group. In relation to independent group designs, when the researcher tests one group of subjects under different conditions or treatments, is known as repeated treatment design. On other hand, when the researcher uses separate groups for all possible treatments separately, is known as between group design. In planning, decision and formulating this type of research design, two conditions or treatment of the independent variable are selected by the researcher with aim to find out its effect on dependant variable. In this kind of design, every participant is treated or assigned to one treatment only. Advantage of between group designs in comparison with repeated treatment designs Usually in health science related researches, between group designs is considered as the best option and highly desirable technique of study. Hence, the research proposal given below is an exemplar of the between group design, with an objective to assess the desirable impact and effectiveness of a novel drug invented which is like to alleviating the morbid nature of obesity. The between group designs lessens the chances of patients suffering from boredom in a series of
