Uri asked six friends how many different foreign countries they’d been to. he recorded 0, 1, 1, 2, 5, and 9 countries visited. what is the mean absolute deviation of countries visited? round to the nearest tenth, if needed.

 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

We have to calculate the mean absolute deviation of countries visited.

So, we know the formula:

Hence, there is mean absolute deviation of countries is 2.7 countries.

2.7 countries
