Answer:The mean absolute deviation (MAD) of the number of pages in the 5 books Rori read =24

Step-by-step explanation:

To find the the mean absolute deviation (MAD,we start firt by

Getting  the mean of all values

Mean =120, 106, 94, 100, 180/5  =600/5=120

Next we subtract the mean value  from each value which is called distance

120 -120  = 0

106 -120 = -14

94 -120=  -26

100 -120=-20

180 -120=60

Thirldly, we find the mean of the distances  ignoring the negative signs

0+14+26+20+60 / 5 = 120/5=24
