ONE-WAY ANOVA
Data from #13-13 pp.520 of "Applied Statistics and Probability for Engineers" Fourth edition by Douglas C. Montgomery & George C.
Runger.
The goal of this experiment was to see if four specific firing temperatures (100, 125, 150 and
175 deg F) had any effect on the density of a certain type of brick. The units for density are
not known. The firing temperatures are being treated as categories rather than quantities.
