Apr 10, 2024 · Study with Quizlet and memorize flashcards containing terms like what are two defining features of an experiment, why do researchers randomly assign participants conditions?, which of the following is a false statement? a. An extraneous variable is any variable other than the independent and dependent variables. b.
An experiment is a type of empirical study that features the manipulation of an independent variable, the measurement of a dependent variable, and control of extraneous variables. Studies are high in internal validity to the extent that the way they are conducted supports the conclusion that the independent variable caused any observed differences in the dependent variable. …
Learning Objectives Explain what an experiment is and recognize examples of studies that are experiments and studies that are not experiments. Distinguish between the manipulation of the independent variable and control of extraneous variables and explain the importance of each. Recognize examples of confounding variables and explain how they affect the internal validity …

Feb 11, 2025 · The two defining characteristics of experimental studies are the manipulation of an independent variable and the control of extraneous variables (often through random assignment) to determine cause-and-effect relationships.
Mar 5, 2025 · Several core characteristics define a study as truly experimental: Manipulation of the Independent Variable (s): The researcher has the explicit ability to control and manipulate the independent variable (s), also known as the treatment or intervention. This is the defining characteristic of experimental research.
Two-Group Experimental Designs The simplest true experimental designs are two group designs involving one treatment group and one control group, and are ideally suited for testing the effects of a single independent variable that can be manipulated as a treatment.
Dec 18, 2024 · Experimental research allows for controlling the effect of extraneous variables. That is, experimental research design can accurately determine if the changes in the dependent variable are indeed caused by the specific independent variable being studied and manipulated.
