## The Effect of Special Preparation on SAT-V Scores in Eight Randomized Experiments

### Description

You've all seen these before. These are the "eight schools" that everyone gets when
being introduced to Bayesian programming. Here are the full data for your consideration,
which you can use instead of awkwardly searching where the data are and copy-pasting
them as a list. Every damn time, Steve.
