A student conducted an experiment to assess the impact of two different watering schedules on the growth of two plant species. Each plant species was divided into two groups: one received daily watering, and the other received weekly watering. The student measured the average height (in centimeters) of each group after 1, 2, and 3 weeks and plotted the data in the attached bar graph.

Based on the data presented in the bar graph provided, which watering schedule had a greater positive impact on plant growth for both species over the three weeks?
