In general, reliability in research refers to consistency in a study or measurement test; validity refers to accuracy.

However, these concepts are much more complex in actual research practice than these broad definitions (validity in particular). The following are very useful resources for more information.

  • Look at the SAGE Research Methods tool in our licensed databases. (You'll need to login with your APUS credentials.) Do individual searches on validity and reliabilty. The results include a range of definitions and explanations in encyclopedia, dictionaries, and handbooks.
     
  • The open web, online text for social science research, Research Methods Knowledge Base, is another solid resource for information on these two important research concepts. The Table of Contents is here: http://www.socialresearchmethods.net/kb/contents.php  Scroll down for the sections on validity and reliability.
