Experimental Study
the researcher manipulates one of the variables and tries to determine how the manipulation influences other variables
An experimental study is a type of research design in which the researcher manipulates one or more independent variables and observes their effects on a dependent variable, while controlling for extraneous variables. This type of study is used to establish cause and effect relationships between variables.
Experimental studies typically involve selecting a sample of participants and randomly assigning them to either a control group or an experimental group. The control group receives no intervention, while the experimental group receives the manipulation of the independent variable. The dependent variable is measured in both groups at the end of the study to compare the effects of the manipulation.
The strengths of experimental studies include their ability to manipulate variables, control for extraneous variables, and establish cause-and-effect relationships. However, they may lack external validity, as they are often conducted in highly controlled environments and may not accurately reflect real-world conditions.
To ensure the validity of an experimental study, it is important to carefully design the study, including selecting appropriate control and experimental groups, clearly defining the variables of interest, and minimizing confounding factors. Additionally, it is crucial to maintain ethical standards in conducting the study, including obtaining informed consent from participants and ensuring that the study does not cause harm to any participants.
