In a science fair project, a student is studying the effect of different types of music on plant growth. What is the role of the plant's growth (height in cm) in this experiment?

• It is the variable that the student manipulates by playing different types of music

• It is the variable that the student measures to determine the effect of music

• It is the variable that remains constant regardless of the type of music played

• It is the variable that is not affected by other variables such as light or water
