I’m always looking to add new resources to this page. If you have a favorite, please brooke{dot]robertshaw{at}gmail[dot}com.

Effect Size resources

General Information sites

  • StatNotes Books: A series of books you can buy that are, in my opinion, one of the best resources for SPSS. Each topic costs $5.00, but you can also download a pdf and request a password to access it for free. This is on a limited basis. They are also available for free through Kindle Unlimited.
    • Note: Having used these, they are very, so very, worth the $5.00
  • Annotated output at UCLA: Output of different tests from STATA, SPSS, SAS, R & MPlus with descriptions what each piece of information given means.
  • Data Analysis Examples at UCLA:Introduction to the essence of different analysis techniques in SPSS, SAS, STATA, MPlus & R.
  • Choosing the right statistical statistic at UCLA: A decision tree for helping to choose the right statistic.
  • Frequently asked questions at UCLA: FAQs for general statistics questions, R, SAS, STATA, SPSS, MPlus, SUDAAN.
  • Handbook of Biological Statistics: Yep, its useful even for those of us in the behavioral sciences.
  • Research in Action Podcast: General discussion about resesearch and interviews with well known researchers, including John Creswell, Neil Salkind, and Jason Osbourne.

Survey research resources


Item Response Theory

  • jMetrik: Free and open source software for running psychometric analysis (item response theory). There is a version for both Mac and PC.
  • IRT Pro: An IRT software just for PC. I’ve used it and really like it. There is a free version that limits the number of cases (up to 1,000) and items that you can have.
  • The Basics of Item Response Theory, by Frank Baker: From what I gather it is one of the key resources on the web for learning IRT.
  • Item Response Theory resources: A page of resources created by the same folks who have made Baker’s book available.
  • A visual guide to item response theory: As I am working to learn IRT this is another resource that is cited over and over.
