Question

Quizplus · Accepted Answer

Manipulation and random assignment are two essential features of an experiment, where the researcher intentionally manipulates the independent variable and assigns participants randomly to different conditions. This allows for establishing cause-and-effect relationships between variables and minimizing the impact of extraneous variables. Naturalistic observation and natural correlations do not involve manipulation or random assignment, and matched-samples correlational designs only manipulate the selection of participants, not the independent variable.
