William Gosset analyzed data from an experiment comparing the yield of regular and kiln-dried corn.

Format

A data frame with 11 observations on the following 2 variables.

reg: yield of regular corn (lbs/acre)
kiln: yield of kiln-dried corn (lbs/acre)

Details

Gosset (Student) reported on the results of seeding plots with two different kinds of seed. Each type of seed (regular and kiln-dried) was planted in adjacent plots, accounting for 11 pairs of "split" plots.
