Question

Find the mean absolute deviation of the number of kittens in 10 litters : 4,5,5,6,6,7,8,8,8,9

Answer 1

Answer:

Step-by-step explanation:

mean=(4+5+5+6+6+7+8+8+8+9)/10=66/10=6.6

x    |x-6.6|

4      2.6  (6.6-4=2.6)

5      1.6   (6.6-5=1.6)

5      1.6

6      0.6  (6.6-6=0.6)

6      0.6

7      0.4 (7-6.6=0.4)

8      1.4  (8-6.6=1.4)

8      1.4

8      1.4

9      2.4  (9-6.6=2.4)

       -----

       14.0

       ------

mean absolute deviation=14/10=1.4
