The other addition in the hypothesis is the word “significant”, meaning that any effect you find is “considerably” larger than the effect you would find if you were not to use Mycorrhizae. You should now note in the hypothesis version of the question that you now include an expectation that the effect will be positive. Mycorrhizae has a significant positive effect on the body size of plants You could also reformulate your very specific question in the form of an hypothesis, like: There are a few other nuances about formulating a question, that we will talk about when we deal with designing the experiment. See for instance, how the question is explicit about fungi, affecting specifically the body size of plants. It could be as simple as:ĭoes Mycorrhizae increase the body size of plants?įor the purpose of the scientific method you need to be very specific in what you want to study. Once you have a clear question, and you are relatively certain that no one has asked the question before, or answer it insufficiently, you should move to the next phase of the scientific method, which is to formulate your question more specifically. The third step in the scientific method for solving a problem is to define the hypothesis. Accepting or rejecting the null hypothesis.
