Twentypercentt of the ice-free areas (available nesting habitat for snow petrels) was surveyed using a "random block design".
Twelve ruminal fistulated non-lactating Holstein cows were offered one of four forage diets (long alfalfa hay (ALH), chopped alfalfa round bale silage (ALS), long orchard grass hay (OGH), and chopped corn silage (CS) with similar dry matter digestibility using a random block design.
The randomisation list was computer generated using a random block size to maximise allocation concealment and was stratified by centre (Nottingham and Derby).
After consent and completion of baseline data collection, the participants were individually randomised using a random block size, stratified by centre and a web-based remote randomisation system into either a 1 week course or a 5 week course.
According to the Kellgren/Lawrence Scale of anterior-posterior (AP) and lateral standing knee radiographs, a random number will be stratified using a random block size of 4. Sequentially numbered, opaque, sealed assignment envelopes will be delivered to each research centre.
We used a random-block experimental design.
For this purpose, 40 ewes' lambs (23.5 ± 1.11 kg initial live weight, LW) were used in a random block design over a 13-week period.
We also considered the possible differences between the two insect lots we used as a random block factor.
We used a random number table in blocks of four to ensure that approximately equal numbers of women were allocated to each group.
The allocation sequence is computer-generated by the UKCRC-registered Peninsula Clinical Trials Unit (CTU) in conjunction with an independent statistician, using a random permuted block design, with blocks of varying sizes.
