## La·tin square

(la'tin sqwār),
A statistical design for experiments that removes from experimental error the variation from two sources that may be identified with the rows and columns of a square. The allocation of experimental treatments is such that each treatment occurs exactly once in each row and column. For example, a design for a 5 × 5 square is as follows: Farlex Partner Medical Dictionary © Farlex 2012

Mullen, Discrete Mathematics Using Latin Squares, John Wiley Ans Sons, Inc., 1998, 305.
A Latin Square of order n is an n by n array containing symbols from some alphabet of size n, arrenged so that each symbol appears exactly once in each row and exactly once in each column.
For a fixed n, all n x n Latin squares have the same mean squared errors (MSE) and are, therefore, equally efficient.
It is known that for a given n, all n x n Latin squares have the same [R.sub.2] value.
Discuss this Latin square with your students, noting that other arrangements are possible.
Back to Sudoku, which has an extra constraint compared with a regular 9x9 Latin square. Each of the nine non-overlapping 3x3 sub-grids along the edges and in the centre of the larger grid must also contain the digits 1 to 9 without repetition.
The number of treatments determines the size of the Latin square. The data are represented by [X.sub.ij(k)] and are [r.sup.2] in number for a Latin square of r rows and r columns.
