However, the researcher must also define exactly what each variable is using what is known as operational definitions. So you could write a hypothesis on anything from how sunlight affects plant growth or cell multiplication to how the amount of income taxes paid impacts one's perception of the president.

In this situation, proof of the falsehood of your hypothesis would occur if the vegetables developed at a very similar pace, irrespective of the type of fertilizer, or if the vegetables on which organic fertilizer was applied developed more rapidly.

Which is why scientists only support or not their hypothesis with data, rather than proving them. For example, prior research has shown that stress can impact the immune system. This type of research method might be used to investigate a hypothesis that is difficult to test experimentally. Just need help assessing the credibility of your sources?
