You buy several bags of balloons. On the package, it says that each bag has 100 balloons. He opens the bags and only one of them has 100 balloons inside; the other bags either have too many or too few. How would you describe this sample of bags?

Accurate but not precise

Explanation:

The sample of balloon bags can be described as being accurate but not precise.

Recall that accuracy is the closeness of measurements to their true values while precision is the closeness of repeated measurement.

The balloon bags are accurate because it appears that the number of balloons in each bag is not far from the actual number of balloons that should be in them - exactly 100 in one and a few off in others. By the time the average number of balloons is calculated, it will not be far off from 100, if not exactly 100.

However, the sample bags are described as not being precise because of the inconsistency or lack of closeness in the number of balloons in each of them.
