Suppose the student's data show that the tomato plants that received the least sunlight produced the heaviest tomatoes. However, the plants that received the most sunlight produced tomatoes with the largest volume. What would be the best thing for the student to do next?

The results differ depending on how tomato size is measured: the least-sunlight plants produced the heaviest tomatoes, while the most-sunlight plants produced tomatoes with the largest volume. The student should revise the hypothesis to specify whether “size” means weight, volume, or another measurement. The results do not show that sunlight has no effect, and contradictory data should not be discarded.
