Answer 2

Confounding is used to reduce the size of blocks

• Confounding is one of the design techniques used in factorial experiments.
• Here the size of Blocks is less than the number of treatment combinations.
• Sometimes it is difficult to perform all the runs in a 2k factorial experiment in one turn.
• Single batch of raw materials may be unable to provide all the runs to check the effectiveness of different situations.
• Blocking is the technique used here to deal with controllable nuisance variables.
• Confounding is the design procedure where the entire factorial processes are divided into blocks.
• Size of blocks is usually less than the number of treatment combinations in one replicate.
