Balanced Incomplete Block (BIB) Definition

An experimental design procedure for rotating a large number of products or items in a test.

Balanced incomplete block, or BIB, is an experimental design and survey sampling methodology intended to uncover connections among variables without additional testing. During this statistical investigation, a set of experimental conditions or survey questions is created and organized into blocks. The blocks are situated in a way that optimizes data collection and analysis, particularly when it comes to exploring relationships and interactions between conditions and questions. BIB is useful to entities with limited resources for testing.

Who relies on a balanced incomplete block?

Researchers, statisticians and survey designers seeking to study multiple variables or factors while controlling potential confounding effects turn to BIB for assistance. This methodology is useful when it is not feasible or practical to test every possible combination of conditions or questions.

Why should I care about a balanced incomplete block?

Understanding BIB designs can be beneficial for researchers and entities dealing with experimental design. That’s because the process allows them to gather data by efficiently exploring relationships between variables or conditions. BIB saves time, resources and participant effort.
