Your literature review should contain some quantitative research articles. The word "quantitative" may not appear in the text of the article, so it up to you to analyze the study design and methods sections to determine what type of article it is.
Journal articles often consist of an abstract (a synopsis of the study) and four major sections that often follow the IMRAD format: an Introduction (the research problem and its context); Method section (the strategies used to answer research questions); Results (study findings); and Discussion (interpretation of the findings).

Quantitative research can include experimental tests, drug trials, intervention and treatment studies, and other studies where data can be gathered and quantified. When searching for a quantitative article look for:
- Statistics
- Charts and Graphs
- Design, Methods, Results, Discussion, or Conclusion sections
