Origins
The basic observed relationship between score and Aw is slightly negative, as is that between score change and Aw.
Neither is strong.
Whilewe do observe lower volatilit with lower Aw coffees, it is important to get a larger look at the data that yields those averages.
We can do this with scatterplots.
Here we see plots of all scores against Aw, all score changes against Aw,pre-shipment scores against Aw, and pre-shipment score changes against Aw.


  Broken down by origin, and within origin by PSS-ARR, the (X,Y) placement can shift, but the overall patterns do not.
