Identifying Qualitative v. Quantative Research Articles

The research assignment for this course requires you to utilize primary (aka original) research articles. Primary research articles largely fall into 2 categories. The majority of your sources need to be quantitative research articles, so its important to be able identifying them in your search results. The chart below compares the characteristics of quantitative research articles versus qualitative research articles, which is another common type of primary research articles.

 

What is an primary research article? How does that differ from review or secondary research? More on that in the box below!

What about Review articles?

During your research, you will find many articles that do not contain primary (or original) research. These are secondary research articles that review, analyze, or summarize existing research on a topic. Their goal is to place the existing research of a topic into context, and help those interested in the topic to see trends and identify finding supported by multiple studies.

While this type of article is extremely helpful for background understanding in a topic, or identifying foundational articles on a topic, they do not meet the article guidelines for the research project in this course.

Below are some tips to help you identify this articles.

  • Look at the title
    • The title will often contain the words: systematic review, literature review, meta-analysis, critical review, or some other variation of "review."
  • How is it classified by the database
    • Many databases (like PubMed) will use icons or labels to identify the article's type - including whether it is a review article, or the type or primary article
  • What does the abstract say?
    • Look at how the abstract summarizes the article. Do they use phrases like "we reviewed X number of articles from the past X years"?
