Blocking reduces unexplained variability. Its principle lies in the fact that variability which cannot be overcome (e.g. needing two batches of raw material to produce 1 container of a chemical) is confounded or aliased with a(n) (higher/highest order) interaction to eliminate its influence on the end product. High order interactions are usually of the least importance (think of the fact that temperature of a reactor or the batch of raw materials is more important than the combination o… WebVariability between blocks can be large, variability within a block should be relatively small In general, a block is a specific level of the nuisance factor A complete replicate of the basic experiment is conducted in each block A block represents a restriction on randomization All runs within a block are randomized 4 Chapter 4

WebJun 19, 2012 · By “fractionating” a design we reduce the number of tests. By “folding” a fraction we double its size to separate confounded interactions / main effects. If you need to separate the AB from the CE interaction, you can fold on factor A (or alternatively on factor B or on C or on E) in order to break the “alias chain.”.
