Blocking is one of those concepts that can be difficult to grasp even if you have already been … See more So how does blocking work in experimental design? Here are the main steps you need to take in order to implement blocking … See more 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…
