Independent vs Dependent Variables

Front

What is an independent variable?

Back

The independent variable is the variable that can be changed or controlled in an experiment to test its effects on the dependent variable.

Front

What is a dependent variable?

Back

The dependent variable is the variable that is measured or tested in an experiment, and it changes in response to the independent variable.

In the equation y = mx + b, which variable is dependent?

Back

y is the dependent variable.

Front

In the equation y = mx + b, which variable is independent?

Back

x is the independent variable.

Front

What does it mean when we say a variable is 'controlled'?

Back

A controlled variable is one that is kept constant to ensure that the results of an experiment are due to the independent variable.

Front

If you change the amount of sunlight a plant receives, what is the independent variable?

Back

The amount of sunlight is the independent variable.

Front

If you measure how tall a plant grows in response to different amounts of sunlight, what is the dependent variable?

Back

The height of the plant is the dependent variable.

Front

What is the purpose of identifying independent and dependent variables in an experiment?

Back

Identifying these variables helps to clarify the relationship being tested and ensures that the experiment is structured correctly.
