"Experimental Research" is based on observed and measured phenomena and derives knowledge from actual experience rather than from theory or belief. This type of research may be referred to as Empirical Research, Qualitative Research, or Quantitative Research. How do you know if a study is experimental? Read the subheadings within the article, book, or report and look for a description of the research "methodology." Ask yourself: Would it be possible to recreate this study and test these results?
Key characteristics to look for:
- Specific research questions to be answered
- Definition of the population, behavior, or phenomena being studied
- Description of the process used to study this population or phenomena, including selection criteria, controls, and testing instruments (such as surveys)
Another hint: some scholarly journals use a specific layout, called the "IMRaD" format, to communicate empirical research findings. Such articles typically have 4 components:
- Introduction: sometimes called "literature review" -- what is currently known about the topic -- usually includes a theoretical framework and/or discussion of previous studies
- Methodology: sometimes called "research design" -- how to recreate the study -- usually describes the population, research process, and analytical tools
- Results: sometimes called "findings" -- what was learned through the study -- usually appears as statistical data or as substantial quotations from research participants
- Discussion: sometimes called "conclusion" or "implications" -- why the study is important -- usually describes how the research results influence professional practices or future studies

You may also wish to try a specific concept term in your database searching. Results will vary because each database uses a slightly different vocabulary.
If you need additional definitions or want to explore other topics in research methodology, please search for the concept in the Sage Encyclopedia of Social Science Research Methods.
