Why do we make statistics so hard for our students?

Welch’s t-test

From Stephen B. Heard’s blog Scientist Sees Squirrel:

If you’re like me, you’re continually frustrated by the fact that undergraduate students struggle to understand statistics. Actually, that’s putting it mildly: a large fraction of undergraduates simply refuse to understand statistics; mention a requirement for statistical data analysis in your course and you’ll get eye-rolling, groans, or (if it’s early enough in the semester) a rash of course-dropping.

Heard argues that:

we consistently underemphasize the single most important thing about statistics: that this complication is an illusion. In fact, every significance test works exactly the same way.

He goes on to explain how statistics classes can be made simpler.
