Critical Appraisal

Evaluating Information (RADAR)

RADAR is a framework that provides questions/concepts to reflect on when selecting information for your research projects. As you review your research, consider RADAR and reflect on the questions asked within each aspect of the framework:

  • Rationale: Why does the information exist? Are different viewpoints incorporated? Is evidence used?
  • Authority: What are the author's credentials and qualifications? What do we know about the author's expertise?
  • Date: When was the information published? Is recent information required for your research, or will older sources work as well?
  • Accuracy: Is the information accurate? Are references cited? Do other sources support the research? Can the research be replicated?
  • Relevance: Does the information answer your research question? Does it fit your needs?

Evaluating Information (CRAAP)

CRAAP Method

Use the CRAAP Test method to determine if a web resource is right for you. Evaluate sources based on the following points:

  • Currency: When was the information published? Is it up to date?
  • Relevance: Is the information what you're really looking for? Who is the material written for: academics, professionals, students, or the general public?
  • Authority: Who published, wrote, or edited the information? Is the author an expert on the topic?
  • Accuracy: Is the information reliable and accurate? Do other sources verify this information?
  • Purpose: What is the purpose of the information? Is it biased to one point of view?
