Question

Explain Blocking and Confounding the 2k factorial design
in two blocks.​

Answer 1

Answer:

Use. 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.
