Balanced incomplete block design (bibd) balanced incomplete block design is a randomized incomplete block design when all treatments appear an equal number of times. In a balanced incomplete block design, the treatments are assigned to the blocks so that every pair of treatments occurs together in a block the same number of times. 1 2 3 4 ;

The block size is smaller than the total number of treatments to be compared in the incomplete block designs. Partially balanced incomplete block design (pbibd) an incomplete block design is said to be pbib design if v treatments are arranged in b blocks, each block contains k treatments (k<v), each treatment occur in.

We now discuss the balanced incomplete block design (bibd) and the partially balanced incomplete block design (pbibd) which are the incomplete block designs. The treatment combinations used in each block should be selected in a balanced manner.

General (contin.) incomplete block design may be defined as a design where all treatments can’t appear together in a block, since the number of plots per block is less than number of treatments general (contin.) consider two design structures: One way of constructing a bibd for any block size r b (2 ≤ r b ≤ r) is by listing.
