Controlled experiments are a type of scientific research design in which researchers manipulate one or more independent variables in a controlled environment to observe the effects on a dependent variable. This method allows researchers to establish a cause-and-effect relationship between variables by minimizing extraneous factors and confounding variables. Controlled experiments are commonly used in psychology, biology, and other scientific disciplines to test hypotheses and determine the influence of specific variables on outcomes.
