Empirical Research Studies

What is an empirical article?

Empirical research articles are scholarly, peer-reviewed journal articles that are based on data collected during the authors' real-life experiments or observations. They are primary research documents that contain either qualitative or quantitative research methods:

  • Qualitative research focuses on collecting in-depth information from small sample sizes in order to describe a trend. Data is typically collected through one-on-one interviews with participants.
  • Quantitative research uses large, representative sample sizes to collect a variety of statistics that can then be generalized. Data is typically collected through a questionnaire, attitude scale, or achievement test.

How can I tell if an article is empirical?

Several factors can help you decide whether or not an article is empirical:

  • What type of journal/magazine was the article published in?
    • Academic journals such as the Medical Laboratory Journal, Clinical Laboratory Science, and the Archives of Pathology and Laboratory Medicine often publish empirical articles.
    • Popular magazines such as Time or Newsweek don't publish empirical articles.
    • Professional journals such as TRANSFUSION or the Journal of Microbiology & Biology Education will publish empirical articles, while professional magazines (e.g., Clinical Microbiology Reviews, Lab Manager, and MEDLAB Magazine) won't publish empirical articles.
  • If there's an abstract available, what does it say?
    • Did the author(s):
      • Administer a survey or questionnaire?
      • Conduct an interview?
      • Collect data?
      • Use an assessment to measure results?
    • Empirical articles include many of the above characteristics.
  • What headings or sections is the article broken down into?
    1. Introduction/Literature Review
    2. Methodology/Research Design
      • This section will include information on how the study was conducted: how it was designed, who the participants were and how they participated, and how the results were measured.
      • This information allows other researchers to replicate the study with their own participants.
    3. Results/Findings
    4. Discussion/Conclusion/Implications
    5. References
    • Although authors might combine some sections, label them differently, or not use any headings at all, empirical articles will contain all of the above information.
  • How long is the article?
    • Because empirical articles contain so many details about their studies, they tend to be longer.
    • They also contain charts, tables, and other graphics to help display the data that was collected.
