It involves manipulating one or more independent variables and observing the effects on a dependent variable while controlling for other factors. Key features of the experimental method include:

  • Random assignment: Participants are assigned randomly to different experimental conditions, ensuring that groups are comparable and any observed differences can be attributed to the independent variable.
  • Control group: A group that does not receive the experimental treatment, serving as a baseline for comparison with the experimental group(s).
  • Variable manipulation: Researchers deliberately alter or manipulate the independent variable(s) to observe their impact on the dependent variable.
  • Measurement and observation: Data is collected through surveys, tests, or observations to assess the influence of the independent variable(s) on the dependent variable.
  • Replication: The study should be replicated by other researchers to validate the reliability and validity of the findings.
