Patients were randomly assigned in a 1:1 ratio to a restrictive or liberal transfusion strategy by means of a Web-based system and a permuted-block design with random block sizes of 4 and 6 ...

In many experimental situations, a response surface design is divided into several blocks to control an extraneous source of variation. The traditional approach in most response surface applications ...

It is instructive to review completely randomized design (CRD) and randomized complete block design (RCBD) 2 and show how these relate to split plot design.

The randomization sequence was computer generated by an independent statistician at the central coordinating site with the use of a permuted block design with a block size of two.

Considered is an unusual split plot design. The whole plot part is a Latin rectangle design, while the split plot part derives from a nonstandard strip block design. For the strip block part, there ...

Presence of sites enrolling fewer than eight patients led to some numerical imbalances among treatment groups due to the randomization block size.
