What is the relationship between the variables on this graph?

• There is no correlation between the variables

• As the points scored increases, then the hours spent decreases.

• As the hours spent practicing increases, then the points scored decreases

• As the hours spent practicing increases, then the points scored increases

An experiment is performed on plants to see how different liquids affect plant growth. Each plant in the experiment is given a different liquid; water, apple juice, or milk. Each plant has the same amount of soil, sunlight, and listens to the same music. In this investigation, the independent variable is ...
