WebbCluster Randomized Trials – ARCHIVED Randomization Methods – ARCHIVED Choosing Between Cluster and Individual Randomization – ARCHIVED Alternative Cluster Randomized Designs – ARCHIVED Concealment and Blinding – ARCHIVED Designing to Avoid Identification Bias – ARCHIVED Additional Resources – ARCHIVED WebbAny experimental design in which the randomization of treatments is restricted to groups of experimental units within a predefined block of units assumed to be internally homogeneous is called a randomized block design. Blocks of units are created to control known sources of variation in expected (mean) response among experimental units.

WebbRandomized Block Designs. Nuisance factors are variables that can affect the outcome, but they are not the researcher’s primary interest. Unfortunately, they can hide or distort the treatment results. When experimenters know about specific nuisance factors, they can use a randomized block design to minimize their impact. WebbAfter using a randomized block design, it is not unusual to find that the block effect is not only not significant, but so small that it would have been better to have not blocked in the first place. It might then be tempting to reanalyze the data using a completely randomized design in order to gain degrees of freedom.
