This chart shows the experimental design of four students who are all observing what kind of bird seed birds tend to eat more often.

Student 1
- Performed the experiment once
- Used the same area, same time of day, and same amount of seeds
Student 2
- Repeated the experiment 5 times
- Used the same area, different time of day, and different amount of seeds
Student 3
- Repeated the experiment 2 times
- Used the same area, different time of day, and different amount of seeds
Student 4
- Repeated the experiment 5 times
- Used the same area, same time of day, and same amount of seeds

Which student is the most likely to have reproducible results?

Student 1
Student 2
