Teaching only usual stuff - t-tests, linear regression (as I studied in my time) is crime I cannot look at the t-test the same way. Below is a stylized graph to show the idea. I consider those error-statistical methods to be essentially Bayesian, whereas thinks of me (or, one might say, the “Bayesian Data Analysis” school) as an exception within Bayesian statistics.
