Although you may have gathered huge amounts of data, there is rarely enough space in an article intended for publication in a journal to write about every aspect. You must, therefore, decide what will be the main subject of this particular paper.

But you also need to be clear what exactly you want to convey about the subject. The clearer you are, the easier it will be to write and the more likely it is to be published.

True, your paper will present data. But which data you select for inclusion, and even how you present it, will be determined by what message or argument you are trying to convey. That message may, for example, be an answer to the hypothesis underlying your study.

Being clear what your message is makes writing an academic or scientific paper easy to do.
