- A hypothesis is a statement that can be proved or disproved. It is typically used in quantitative research and predicts the relationship between variables.
- A thesis statement is a short, direct sentence that summarizes the main point or claim of an essay or research paper. It is seen in quantitative, qualitative, and mixed methods research. A thesis statement is developed, supported, and explained in the body of the essay or research report by means of examples and evidence.
NOTE: In some disciplines, the hypothesis is referred to as a thesis statement! This is not accurate but within those disciplines it is understood that “a short, direct sentence that summarizes the main point” will be included.
A good hypothesis will be written as a statement or question that specifies:
See some examples:
I am writing my dissertation, and things came out somewhat different to what I had thought three years ago. Back then, I had three hypotheses. Two turned out to be true. The third, last and flimsiest, looks false. The question is: how should I describe the third hypothesis in the short list of hypotheses?
I could phrase it the other way around, as if I always thought it was untrue. There a billion problems to that, the least being: how does one then describe the experimental plan? I can’t really say I wanted the null hypothesis to come true? Surely different kinds of experiments would have been more useful.
