Research Basics: Identifying Research Studies

What are the different types of research studies?

Research studies are typically published in scholarly (or academic) journal articles

Original Research

Original Research
  • Researchers in a field of study propose a hypothesis and use defined methods to provide evidence that either supports or does not support the hypothesis. 

    • Sciences and social sciences
      • Researchers design and conduct an experiment in order to gather evidence
    • Humanities
      • Researchers use texts, historical events, theories, and/or artifacts to provide new understandings of a topic or work
  • Also called Primary or Empirical Research
  • Often peer-reviewed

Research Review

Research Review
  • Researchers in a field of study provide a summary and synthesis of previous research on a topic or question to provide a rationale for additional exploration.    
  • Sometimes called a Literature Review
    • Can be a standalone article
    • Can also be a section within an original research article, typically the Introduction section
  • Systematic review (often used in medical fields) uses a comprehensive review of the research to answer a particular research question
    • Often combined with Meta-Analysis
  • May be peer-reviewed

Meta-Analysis

Meta-Analysis
  • Researchers in a field of study conduct quantitative statistical analysis on the data from two or more original research studies which have similar designs or outcomes.  
    • Not considered Original Research
    • Typically uses the results of a Systematic Review
    • Researchers use the statistical analysis to determine reliability of data. 
  • Also called Research Analysis
  • Due to its quantitative nature, not typically a research strategy for the Humanities
  • May be peer-reviewed

What is a peer-reviewed article?

A peer-reviewed article is:

  • A scholarly article written by experts in a particular field of study  
  • Read and critiqued by other experts before publication
  • Containing research checked for accuracy and validity before publication  
  • Not published if the peer-reviewers do not accept the research methodology or the findings

Using peer-reviewed research is essential to understanding the most valid research in a field of study.
