[FinB] Shаistа, а behaviоr analyst, wants tо test оut three different interventions to see which of the three produces the highest number of tasks completed: (a) high-fives delivered following the completion of every task, (b) a tangible given for every five tasks completed, and (c) a 60-second break given after every ten tasks completed. Shaista is careful that she does not always run the high-five intervention first, followed by the tangible intervention, followed by the break from tasks intervention, but instead mixes up the sequence in which she runs each intervention. Which consideration is Shaista addressing when using a multielement design?
