Quizplus · Accepted Answer

An experiment is the best research method to investigate cause and effect relationships between variables because it allows the researcher to manipulate one variable (independent variable) to observe its impact on another variable (dependent variable), while controlling for other variables. This enables the researcher to establish a cause-and-effect relationship between the two variables being studied. Observation and correlation cannot establish causality, while case studies are limited to specific individuals or situations and cannot be generalized to larger populations.
