Review IV/DV for Variables Flashcard

Front

What is a dependent variable?

Back

A dependent variable is the outcome or response that is measured in an experiment. It is affected by changes in the independent variable.

Front

What is an independent variable?

Back

An independent variable is the factor that is manipulated or changed in an experiment to observe its effect on the dependent variable.

Front

In an experiment, what does the term 'manipulated variable' refer to?

Back

The manipulated variable is another name for the independent variable, which is intentionally changed to test its effects.

Front

What is the purpose of a control variable in an experiment?

Back

Control variables are factors that are kept constant to ensure that any changes in the dependent variable are due to the independent variable.

Front

How do you identify the dependent variable in a research question?

Back

The dependent variable is usually the outcome you are measuring, often found in the question's phrasing, typically after 'affects' or 'influences'.

Front

What is the relationship between independent and dependent variables?

Back

The independent variable is what you change, and the dependent variable is what you measure in response to that change.

Front

Give an example of a dependent variable in a study about studying methods and test scores.

Back

Test scores would be the dependent variable, as they are measured to see how they are affected by different studying methods.

Front

What is the significance of having a clear independent variable in an experiment?

Back

A clear independent variable helps to establish a cause-and-effect relationship, making the experiment's results more valid.

Front

What does it mean if an experiment has multiple independent variables?

Back

Having multiple independent variables can complicate the experiment, as it may be difficult to determine which variable is affecting the dependent variable.

Front

Why is it important to define variables clearly in an experiment?

Back

Clear definitions of variables help ensure that the experiment can be replicated and that the results are understandable.
