An abstract is a summary of the main article. An abstract will include information about why the research study was done, what the methodology was and something about the findings of the author(s). The abstract is always at the beginning of the article and will either be labeled "abstract" or will be set apart from the rest of the article by a different font or margins.

The abstract should tell you what the research study is about, how the research was done (methodology), who the research sample was, what the authors found and why this is important to the field.
