Experimental Methods refer to a set of procedures and techniques used in scientific research to investigate causal relationships between variables. These methods involve manipulating one or more independent variables while controlling other factors to observe the effects on dependent variables. Experimentation allows researchers to test hypotheses, establish cause-and-effect relationships, and gather empirical evidence to support their theories. Common experimental methods include randomized controlled trials, laboratory experiments, field experiments, and quasi-experiments. These methods often involve the collection and analysis of quantitative data to draw conclusions about the relationships between variables.
