Experimental research is a type of study which is commonly used in scientific research designs, and it is the primary approach used to scrutinize the causal (cause/effect) relationships and investigate the relationship between one variable and the other. This kind of research is known as a hypothesis testing or a deductive research method [1] because it is used to support or disprove the hypotheses which are formulated by the researcher to address a specific question or issue [2 & 3].

Kinds of experimental designs: Pre-experimental, quasi-experimental, and true experimental designs are the three basic kinds of experimental research designs. A special type of experimental design is determined by the degree to which the researcher assigns subjects to the different conditions and groups [4]. The first and basic kind of experimental design is the pre-experimental design in which the basic experimental steps are followed, but there is no control group. By using this design, the researcher studies a single group and does not make any comparisons between this group and an equivalent non-treatment group [5]. A quasi-experimental design is the second kind of research that looks a little like an experimental design but the subjects are not randomly assigned to the groups [6]. The third and the most important type of experimental design is the true experimental design which is considered as the most accurate type of the experimental research because it uses statistical analysis to support or reject a hypothesis. This kind of design is also regarded to be the only experimental design that can assess cause and effect relationships [7]. Therefore, different types of the true experimental designs are listed below:
To put it simply, experimental research is aimed at drawing conclusions through controlling the extraneous factors so that the researcher can provide definite conclusions with regard to the effect of the independent variable on the dependent one. References:
What type of research design has two independent variables?In factorial research designs, experimental conditions are formed by systematically varying the levels of two or more independent variables, or factors. For example, in the classic two × two factorial design there are two factors each with two levels.
Can you have 2 independent variables in an experiment?Can I include more than one independent or dependent variable in a study? Yes, but including more than one of either type requires multiple research questions.
What does 2x2 experimental design mean?A 2×2 factorial design is a type of experimental design that allows researchers to understand the effects of two independent variables (each with two levels) on a single dependent variable.
What are the 2 main types of experimental research design?There are two basic types of research design: True experiments. Quasi-experiments.
