A balanced latin-square design is a modified version of the latin-square design. The balanced design is invented in order to account for first order carry-over effects (e.g. learning, fatigue, contrast). The balanced latin-square design follows a designated algorithm which decides on the sequence in which manipulations will be executed. With a size of 4 a balanced Latin-Square design will look as follows: A B D C B C A D C D B A D A C B This ensures that a manipulation will be followed by a different manipulation in the other sequence.
