Elena is interested in whether music affects plant growth. For a science fair project, she will grow one plant in a room that is normally kept quiet. She will grow another plant in another room that has classical piano music playing all the time. After 2 months, she compares the height of the plants to determine the effect of music on plant growth. What type of study is Elena designing? How could her design be improved to collect data that would be better for answering the question of interest?
