Verified step by step guidance1
Understand the key components of an experiment in psychology: manipulation of variables, observation of effects, and control of other variables.
Recognize that an experiment involves an investigator actively changing one or more independent variables to see how they affect a dependent variable.
Identify that controlling other relevant variables (extraneous variables) is crucial to ensure that the observed effects are due to the manipulation and not other factors.
Differentiate an experiment from other research methods such as case studies (detailed observation without manipulation), surveys (self-reported data collection), and correlational studies (examining relationships without manipulation).
Conclude that the best definition of an experiment is a research method where the investigator manipulates variables to observe effects on behavior or mental processes while controlling other variables.
