To investigate the effect of a substance on plant growth, 2 bean plants of the same species were grown under identical conditions with Substance Z added to the soil of one of the plants. At the end of 2 weeks, the plant grown with Substance Z was 15.5 cm tall. The plant grown without Substance Z was 9.2cm tall. The researcher concluded that the presence of Substance Z causes the plants to grow taller.
