Answer :
Answer:
Mean Absolute Deviation=4
Step-by-step explanation:
Given the number of river otters observed on each acre of land in a state park:
0,10,14,6,0,8,4
Mean
[tex]=\dfrac{0+10+14+6+0+8+4}{7} \\=\dfrac{42}{7} \\$Mean,$ \bar{x}=6[/tex]
Mean Absolute Deviation
[tex]M.A.D.=\dfrac{|6-0|+|6-10|+|6-14|+|6-6|+|0-6|+|6-8|+|6-4|}{7} \\=\dfrac{6+4+8+0+6+2+2}{7} \\=\dfrac{28}{7}\\\\M.A.D=4[/tex]
Interpretation: On average, in each park, there is a deviation of 4 from the mean value.
