Amanda is an RBT at an ABA health center. She is running along with her client, Jerrell, to
lower competitive behaviors (i.E., biting others). She has accrued records for the frequency
of Jerrell's bites for 3 weeks. Calculate the suggest, median, and mode of the following
information set (spherical up to the closest entire range):
Week 1: 12, eleven, 10, 22, 22
Week 2: 7, 8, 13, 21, 17
Week three: 16, 7, nine, three, 0 - ANSMean =12, Median = eleven, Mode = 7, 22
