I love sharing a great resource, don’t you?

Today, I stumbled onto Study Design 101   at https://himmelfarb.gwu.edu/tutorials/studydesign101/index.html

If you’re a research afficianado, then you probably already know that some types of research studies are considered stronger than others.   Stronger ones are those that support a hypothesis that X really did cause a change in Y.  [For example, study results that suggest that a pain script (X) really does improve patient satisfaction with pain management (Y)]

You may even know that meta-analyses of randomized controlled trials are the strongest type of research evidence and that case studies are considered the weakest.  (Expert opinion that is not research at all is even below that.)

But….are you clear on what a meta-analysis, a case study, a cohort study or a randomized controlled trial is?   If not or if you want a review, Study Design 101 is for YOU!   Check it out.  Short descriptions followed by 2 question quizzes for self-testing will keep you on track.   Enjoy.
