In the context of a graph, what does the independent variable represent?

Back

The independent variable is typically plotted on the x-axis and represents the input or cause.

Identify the dependent variable in the statement: 'The height of a plant depends on the amount of sunlight it receives.'

Back

The dependent variable is the height of the plant.

Front

Identify the independent variable in the statement: 'The height of a plant depends on the amount of sunlight it receives.'

Back

The independent variable is the amount of sunlight.

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

In an experiment, if you change the amount of water given to plants, what is the independent variable?

Back

The independent variable is the amount of water.

Front

In an experiment, if you measure the growth of plants based on different fertilizers used, what is the dependent variable?

Back

The dependent variable is the growth of the plants.

Front

How can you identify the independent variable in a problem statement?

Back

Look for the variable that is being changed or controlled.
