Front

What is the relationship between independent and dependent variables?

Back

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

Back

The dependent variable is the height of the plant.

Front

What does it mean if a graph shows a positive correlation?

Back

A positive correlation means that as the independent variable increases, the dependent variable also increases.

Front

What does it mean if a graph shows a negative correlation?

Back

A negative correlation means that as the independent variable increases, the dependent variable decreases.
