| The Latin Square design
is a type of experimental
design that allows blocking
in two variables:
| |
Operators
(second blocking variable ) |
| Material
Batch (first blocking variable ) |

The treatments are represented by the Latin
letters 'A', 'B' etc.
The design is restrictive because the number
of classes of each blocking variable must
equal the number of treatments. It is appropriate
for eg. testing crops because the land can
be organized into the appropriate number
of 'blocks'.
