Question

Rori read 5 books last month. Here are the number of pages in each book that she read. (120, 106, 94, 100, 180) What is the mean absolute deviation (MAD) of the number of pages in the 5 books Rori read?

Answer 1

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

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
