Incomplete-block designs

If the experimental units are not all alike, we group them into blocks in such a way that units within each block are tolerably alike. Usually we do this in such a way that all blocks have the same size. Blocks may be fields on different farmers' farms, or groups of patients looked after by different nurses, or laboratory procedures done on different days.

If the blocks are too small to contain every treatment, the design is an incomplete-block design.
