Define a dependent variable in the context of an experimental study. In your explanation, identify what it represents in a causal relationship and describe how it is used by researchers in relation to the independent variable.
Question: Define a dependent variable in the context of an experimental study. In your explanation, identify what it represents in a causal relationship and describe how it is used by researchers in relation to the independent variable.
Sample answer: A dependent variable is the factor in an experiment that represents the presumed effect within a causal relationship. It is the variable that researchers measure to evaluate if it changes as a direct result of the manipulation of the independent variable.
Key points:
- Defines the dependent variable as the factor representing the presumed effect.
- Identifies it as the variable measured in the experiment.
- Explains its role in evaluating changes caused by the manipulation of the independent variable.
Rubric: The response must define the dependent variable as the factor representing the presumed effect in a causal relationship and state that it is measured to evaluate if it changes as a direct result of manipulating the independent variable.

A social psychologist wants to determine if the number of bystanders present during an emergency affects how long it takes for an individual to help. The psychologist stages an emergency in a public space and systematically varies whether there are one, three, or ten other people present. The researcher then measures the time it takes for a participant to intervene and offer assistance. In this experiment, what is the dependent variable?

A researcher randomly assigns participants to either a quiet room or a noisy room and asks them to study a list of 30 vocabulary words for 10 minutes. Afterward, all participants complete a written recall test. The researcher records how many words each participant correctly recalled. In this experiment, the number of words correctly recalled is the _____, because it is the factor measured to evaluate whether the manipulation of the environmental condition produced a change.
