Blocking on an experiment is used to control known variance. If the knownvariance is significant, the blocking factor will show up in the analysis with a p-value less than the level of significance. If there is a known variance and you doNOT block on this factor, what happens to its affect-the variability caused by thisfactor?If you do not randomize your experiment, its affect will manifest itself as a lurking, orlatent-potential, variableIts affect is spread evenly throughout the design if you randomize your experimentIt will have no effect on the analysisIts effect falls under the Error term in the analysis The ACME golf ball company believes they have created a golf ball that will travel25 yards further than the top brand--Brand X.
