When a researcher manipulates a variable to see what effect the manipulation has on another variable, the research design is a(n) experimental method
To establish cause and effect linkages, the experimental approach manipulates variables. The use of controlled methodologies and the assignment of participants at random to control and experimental groups are the main characteristics.
An experiment is a study in which a theory is put to the test in a scientific manner. In an experiment, the cause, the independent variable, is changed while the effect, the dependent variable, is measured and any unrelated factors are controlled.
