I have shared  AMPLE examples for teaching correlations . Because I've got you, boo. Like, I have shared days' worth of lecture material with you, my people. I am adding one more example. I have used this example in my positive psychology course for years, and it really illustrates what can happen en masse when marketing departments and less-savory pop-psych elements try to establish causal relationships with features (stereotypes?) of happy countries and individuals' subjective well-being. I like this one because it is math-free, UG-accessible, and not terribly long. Joe Pinsker, writing for the Atlantic, argues that... https://www.theatlantic.com/family/archive/2021/06/worlds-happiest-countries-denmark-finland-norway/619299/ TL;DR: Just because Northern European nations consistently score the highest on global happiness data doesn't mean that haphazardly adopting practices from those countries will make you happy. Correlation doesn't equal causation. H ere is the ...

They are great ways to illustrate 1) basic, intro stats topics, 2) excellent sci-comm, and 3) psych-adjacent medical examples.  I learned about a recent JAMA publication on NPR (which you could play for your students) . It compared blood pressure in people who were in a Tai Chi exercise condition versus an aerobic exercise condition: https://jamanetwork.com/journals/jamanetworkopen/fullarticle/2814872 Here are some ways you could use it in class: 1. Simple factorial ANOVA research design. Two groups with a repeated measure design makes me think "factorial ANOVA."  I have not, but it would be easy to make a 2 x 2 bar graph with this data (the actual data is embargoed until December).  2. Active control group : The control group wasn't sitting on a couch. The control group was doing aerobic activities.  3. Lots of outcomes and potential for significance (and Type II error) : The main thrust of this pap...
