, 1. Which of the following research methods is the most effective for
testing cause-and-effect relationships?
a) Experimental method
b) Correlational method
c) Observational method

cause-and-effect relationships between variables more effectively.

experimental research?
a) It ensures that participants are representative of the population.
b) It minimizes participant biases.

Answer: c) It balances out individual differences across groups.
Rationale: Random assignment helps in creating equivalent groups,
thereby reducing the impact of individual differences on the results. This
allows researchers to attribute any differences in outcomes to the
manipulation of the independent variable.
3. Which research method is most appropriate for investigating the
relationship between two variables when experimentation is not feasible?
a) Correlational method
b) Case study method
c) Longitudinal method
d) Experimental method
