For math, science, nutrition, history A Latin Square is a n x n grid filled by n distinct numbers each appearing exactly once in each row and column. – Every row contains all the Latin letters and every column contains all the Tutorial on Design of Experiments (RCBD, Split-Plot, Latin Squares, 2^k Factorial) and how to analyze these designs in Excel. There are some similarities between the Williams Design and the Latin Square. Specifically, a Latin square consists of n sets of the numbers 1 to n arranged in such a way that no orthogonal (row or column) contains the same number twice. g. As you fill out the Latin Square it will hide the elminated solutions — you can also hover over a node to A Latin square design is a design in which two gradients are controlled with crossed blocks, but in each intersection there is only one treatment level.
