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?
