Researchers assess people's performances with respect to a given behavior at the beginning of a study before manipulating a variable so they can identify what happens to behavior when they manipulate a variable.The use of control groups and groups that experience a manipulation of a variable is characteristic of
A)correlational studies.
B)longitudinal research.
C)naturalistic observation.
D)experimental research.

Question

Quizplus · Accepted Answer

Experimental research involves manipulating a variable and comparing the outcomes of a control group with a group that experiences the manipulation. The use of control groups and variable manipulation is key to experimental research, making it the best choice for this scenario. Correlational studies focus on relationships between variables, longitudinal research follows a group over time, and naturalistic observation involves observing behavior in its natural setting without manipulation of variables. None of these research methods specifically involve manipulations of variables and control groups in the same way as experimental research.
