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

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)
