The scientist wrote down all of the heights taken into a table. At the end of the experiment he organized the info into a graph.
The scientist set up 4 groups of plants and exposed them to DIFFERENT KINDS OF MUSIC.
Every week the scientist measured the height of the plants.
If plants listen to classical music, then their height will increase.
The scientist used the same kind of plants, in the same kind of pot with the same kind of soil. They were kept at the same temperature, exposed to the same amount of sunlight and given the same amount of water.
