WebThe purpose of this paper is to demonstrate and describe why alternating treatments design (ATD) researchers should consider employing a no-treatment series during the alternating treatments phase. To identify limitations associated with excluding this design element, we obtained examples of ATD studies published in five school psychology … WebAn alternating series is a series ∑ n = 1 ∞ a n where a n has alternating signs. Notice that if a n has alternating signs, we will be able to let b n = a n , and write a n = ( − 1) n b n or a n = ( − 1) n − 1 b n . For instance, has terms a n = ( − 1) n − 1 n and b n = 1 n. then the series converges.
