In its simplest terms an experiment can be defined as study or a process through which there data is collected (Ott & Longnecker, 2010, p.16). The results to be derived from the experiment are however not supposed to be known in advance. Statistical experiments are carried out when the researchers are able to influence the conditions under which the experiment is to be carried out (Berthold & Borgelt, 2010, p. 6). They also can influence the factors that are core to the objectives of the research being carried out. Experimental design, on the other hand, refers to as the process through which planning of a study is carried out so that to ensure the objectives of study are achieved.
Experimental designs can be divided into three different classifications. One of these is the quasi-experimental design. This design is like an ordinary experimental design but is in devoid of a major characteristic; it does have random assignment to their treatment or control (Trochim, 2006). They are used to make empirical studies to determine casual impact that an intervention has on the targeted population. Notably, most people choose quasi-experiments over true experiments as the former can be conducted but that is not always the case for the former. The quasi-experiments are thus credited for being able to bring out features from both the experimental and the non-experimental designs. The quasi-experiments also have the capacity to make use of the measured variables as well as manipulated variables. They are also preferred as they are capable of maximizing the internal as well as external validities (O'Sullivan, Rassel & Berner, 2008).
In respect to the descriptions offered, the best design to make use of in this study is thus the quasi-experimental design as opposed to the true experiments. Despite the fact that these designs does not provide for random assignments, it will be able to make use of the manipulated variables. The study also has internal and external validities thus necessitating the use of this design opposed to true experiments.
