The experimental method of study design is the quantitative approach with the highest level of control. The most manipulative type of research is experimental research since it yields the most valuable outcomes and the most precise answers on which elements genuinely influence others and how. A randomized, double-blind, placebo-controlled trial would provide the utmost degree of control over the variables being studied. This kind of research would produce the fewest erroneous conclusions possible due to the fact that the participants in the study would be chosen at random for the treatment or intervention, and neither the patients nor the researcher would be aware of whether the participants were receiving the treatment or the placebo. Pre-experimental research is the simplest type of research, and it is carried out by observing a group or groups of dependent variables after the treatment of an independent variable that is presumed to cause change on the group. This type of research falls under the category of experimental research. Other types of experimental research include The second type is known as the Quasi type of experimental research, which is very similar to the true experimental research method, but uses subjects that have been carefully selected rather than randomized. The third type is known as the True experimental research method, which is the type that yields the most accurate results and may simply be referred to as experimental research. It does this by manipulating a control group in the direction of a group of subjects who were chosen at random, and it records the effect of this manipulation. There is no manipulation of an independent variable, there is no requirement for a control group, and there are no random group assignments in nonexperimental research. These elements are included in experimental and quasi-experimental designs, respectively. Consider the question, “What influence does caffeine have on nursing medication errors?” as an illustration.
