Where do you find the hypothesis in a research study?
The first few paragraphs of a journal article serve to introduce the topic, to provide the author’s hypothesis or thesis, and to indicate why the research was done. A thesis or hypothesis is not always clearly labled; you may need to read through the introductory paragraphs to determine what the authors are proposing.
