Question

Quizplus · Accepted Answer

Control over extraneous variables allows the researcher to isolate the specific variable being tested, which is not possible in observational or correlational methods. Random assignment ensures that each participant has an equal chance of being assigned to any group, which increases the likelihood that any observed differences are due to the manipulated variable rather than pre-existing differences between groups. Representative sampling and probability levels are important in research design but are not unique to the experimental method. Correlation coefficients and dependent variables are relevant to correlational research but not necessarily to experimental research.
