Answer: there is mean absolute deviation of countries is 2.7 countries
Step-by-step explanation:
since we have given that
0, 1, 1, 2, 5, and 9 countries visited.
so, Mean of all countries visited is given by
\(\sum x=\frac{0+1+1+2+5+9}{6}=3\)
We have to calculate the mean absolute deviation of countries visited.
So, we know the formula:
\(Mean\ deviation=\sum\mid x_i-\bar{x}\mid\\\\\frac{(0-3\mid+(1-3)+(1-3)+(2-3)+(5-3)+(9-3)}{6}\\\\=\frac{\mid-3-2-2-1+2+6\mid}{6}\\\\=\frac{16}{6}=2.7\ countries\)
Hence, there is mean absolute deviation of countries is 2.7 countries.
