Step # 3. Analysis and Results. The analysis result is shown in Figure 7. Figure 7. Latin Square Design Analysis Output. We reject the null hypothesis because of p-value (0.001) is smaller than the level of significance (0.05). Step # 4. Contextual Conclusion.

Unlike RCBD's, Latin Squares are not complete designs; they are an example of an incomplete blocked design. A Latin Square with treatments assigned to the first row and the first column in an alphabetical or numerical sequence is called a standard square. Figure 1 shows the standard squares for 2 x 2, 3 x 3 and 4 x 4 designs.

Statistical Analysis of the Latin Square Design. The statistical (effects) model is: Y i j k = μ + ρ i + β j + τ k + ε i j k { i = 1, 2,., p j = 1, 2,., p k = 1, 2,., p. but k = d ( i, j) shows the dependence of k in the cell i, j on the design layout, and p = t the number of treatment levels. The statistical analysis (ANOVA) is.

Like the RCBD, the latin square design is another design with restricted randomization. Random-ization occurs with the initial selection of the latin square design from the set of all possible latin square designs of dimension pand then randomly assigning the treatments to the letters A, B, C,:::. The following notation will be used:

Latin rectangles and multiple Latin squares. Sometimes, one Latin square is not quite enough. In fact, it is often held that if a ≤ 4 , and then more than one square should be considered in a design. On the other hand, when a ≥ 8 , a Latin square may be considered to be too large of an experiment.

Latin square (and related) designs are efficient designs to block from 2 to 4 nuisance factors. Latin square designs, and the related Graeco-Latin square and Hyper-Graeco-Latin square designs, are a special type of comparative design. There is a single factor of primary interest, typically called the treatment factor, and several nuisance factors.

Latin Square Design. Design commonly represented as a p × p grid. There are now two randomization restrictions. One trt per row (row = Block1 factor) One trt per column (column = Block2 factor) Can randomly shuffle rows, columns, and treatments of "standard square" to get other variations of layout. The "standard square" has treatment.

Latin Square Designs. A Latin square design is the arrangement of t treatments, each one repeated t times, in such a way that each treatment appears exactly one time in each row and each column in the design. We denote by Roman characters the treatments. Therefore the design is called a Latin square design.
