When selected orders of conditions (Latin Square or random starting order with rotation)are used to balance practice effects in the incomplete repeated measures design,
A) the number of selected orders must be exactly equal to the number of conditions in the experiment.
B) the number of selected orders will always be equal to some multiple of the number of conditions in the experiment.
C) the number of selected orders will always be equal to one less than the number of conditions in the experiment.
D) there is no restriction on the number of possible orders needed to balance practice effects in the incomplete repeated measures design.

With selected orders of conditions, the number of orders needed to balance practice effects will be a multiple of the number of conditions in the experiment. This is because each condition must be paired with every other condition an equal number of times in order to balance any potential practice effects. Therefore, the number of orders needed will depend on the number of conditions being studied.
