The primary goal of designing a randomized block experiment is to reduce the within-treatments variation in order to more easily detect differences among the treatment means. This is achieved by grouping similar experimental units into blocks and randomizing the treatments within each block, which helps to reduce the effects of any confounding variables that may be present. By doing so, the treatment effects can be more accurately measured and compared.
