What is a dependent variable?

Back

A dependent variable is a variable that is measured and affected in an experiment. It depends on the independent variable.

In an experiment, if the height from which a ball is dropped is changed, what is the dependent variable?

Back

The x-axis represents the independent variable.

Front

In the context of a road trip, if distance is dependent on time, what is the independent variable?

Back

The independent variable is time.

Front

What does it mean if a variable is dependent?

Back

It means that the variable's value is influenced by changes in another variable.

Front

What is the relationship between independent and dependent variables?

Back

The independent variable is manipulated to observe its effect on the dependent variable.

Front

If Daisy runs further, what happens to the time spent running?

Back

The time spent running (dependent variable) increases as the distance run (independent variable) increases.

What is an example of an independent variable in a science experiment?

Back

The amount of sunlight a plant receives is an independent variable.
