The Relationship Between the Analysis of Simple Cross Over Design And the Analysis of Compound Set of Youden Squares

The cross over design with a missing period was split into a set of Youden squares. A direct and indirect methods were applied before and after splitting and a comparation between the results was established. The data have been generated according to an experiment conducted in cross over design which was applied in the college of Agriculture and Forestry, University of Mosul.The analysis of a set of Youden squares showed a better results through the direct method according to comparative measurements: rising the F value, decreasing both the significant level ( ) and the mean squares error (MSe). Also the analysis of a set of Youden squares showed better results than cross over design analysis through both analytical methods according to the comparative measurements.
