248 PART III: Experimental MethodsAnswer to Challenge Question 1A Assigning the values 1, 2, and 3 to the Low, Medium, and High conditions, respectively,and using the first row of the random number table (Table A.1) in the Appendixbeginning with the first number in the row, the block-randomized sequence is Low-High-Medium- Low-Medium-High. One possible ABBA counterbalanced se quence isLow-Medium-High- High- Medium-Low.B Because there are six conditions, all possible orders are not feasible. Therefore, either a LatinSquare or a random starting order with rotation is needed to balance practice effects. A possibleset of sequences using rotation isPositionParticipant 1st 2nd 3rd 4th 5th 6th1 8 10 11 9 7 122 10 11 9 7 12 83 11 9 7 12 8 104 9 7 12 8 10 115 7 12 8 10 11 96 12 8 10 11 9 7
