Batch yield and purityThe two columns in the data set are:
  1. the percentage yield from a batch reactor, and
  2. the purity of the feedstock.

The feedstock is what we add to the reactor, and the yield is measured after the reaction is completed.

The cause-and-effect direction is that the purity of the feedstock has (potential) impact on the yield.
