MGMT 2110 - Organizational Behavior (Fall 2019): Evaluate Information - RADAR

RADAR represents 5 criteria

The world is full of information to be found; however, not all of it is valid, useful, or accurate. So, how can you determine which is good information and highly relevant to your research papers? 

Use RADAR -- a method to help you evaluate information critically!  It represents 5 criteria:

Relevance (the importance of the information for your needs)

  • How is the information that you have found relevant to your assignment?
  • Does the information answer your research question?

Authority (the source of the information)

  • Who is the author/publisher/source?
  • What are the author's credentials? Is the author affiliated to an academic institution or reputable organization? Does the author have good qualifications and experience? Is the author an expert in his/her field?
  • Does anyone else cite the author?

Date (the timeliness of the information)

  • When was the information published?
  • Has the information been revised or updated?
  • Is the publication date important to you? Does your research require timely sources? In some disciplines, the currency of the information is very important, while in others it is less so.

Accuracy (the reliability, truthfulness, and correctness of the information)

  • Where does the information come from?
  • Is the information supported by evidence?
  • Has the information been peer-reviewed or gone through an editing process?
  • Is the information presented in a professional or academic manner? Is it free from spelling errors? Is the text well-written and grammatically correct?
  • Does it have citations and references? Are they mostly authoritative or helpful sources? Can they be verified elsewhere?

Rationale/Reason for writing (the reasons the author wrote/published the information)

  • Why did the author publish the information?
  • Was it written to inform, educate, persuade, advertise, or entertain?
  • Was it a new research combing previous findings from related studies?
  • Is there obvious and/or extreme bias or prejudice?
