Order effects occur when a participant in an experiment is able to perform a task and then perform it again at some later time. Generally, they either have a positive (subjects become better at performing the task) or negative (subjects become worse at performing the task) effect. Repeated measures designs are almost always affected by order effects; the primary exception to this rule is in the case of a longitudinal study. How well these are measured is controlled by the exact type of repeated measure design that is used. To counteract order effects there is a method which you can use called counter balancing.
Examples of order effects are as follows: practice, boredom and fatigue which can compromise the reliability (consistency) of the results.

Famous quotes containing the words effects and/or order:
“Virtues are not emotions. Emotions are movements of appetite, virtues dispositions of appetite towards movement. Moreover emotions can be good or bad, reasonable or unreasonable; whereas virtues dispose us only to good. Emotions arise in the appetite and are brought into conformity with reason; virtues are effects of reason achieving themselves in reasonable movements of the appetites. Balanced emotions are virtues effect, not its substance.”
—Thomas Aquinas (c. 12251274)
“All grandeur, all power, all subordination to authority rests on the executioner: he is the horror and the bond of human association. Remove this incomprehensible agent from the world and at that very moment order gives way to chaos, thrones topple and society disappears.”
—Joseph De Maistre (17531821)
