Independent and Dependent Variables

Front

What is an independent variable?

Back

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

Front

What is a dependent variable?

Back

The dependent variable is the factor that is measured or observed in an experiment, which is affected by changes in the independent variable.

Front

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

Back

Controlled variables are the factors that are kept constant throughout an experiment to ensure that the results are due to the independent variable.

Front

How do you identify the dependent variable in a question?

Back

The dependent variable is usually the outcome or effect that is being measured in response to changes in the independent variable.

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 as a result of that change.

Example of an independent variable in a study about plant growth?

Back

The amount of sunlight the plants receive.

Front

Example of a dependent variable in a study about plant growth?

Back

The height of the plants after a certain period.

Front

Why is it important to control variables in an experiment?

Back

Controlling variables ensures that the experiment is fair and that the results are valid, isolating the effect of the independent variable.

Front

What is a hypothesis in the context of independent and dependent variables?

Back

A hypothesis is a testable statement predicting the relationship between the independent and dependent variables.

Front

How can changing the independent variable affect the dependent variable?

Back

Changing the independent variable can lead to changes in the dependent variable, which can be observed and measured.
