Question

If a data set has only one outlier, which value will always change when the outlier is excluded?

Answer 1

I don't think the value will change when the outlier is excluded

Explanation:

Do it like an other problem

Answer 2

Mean and the range

Explanation:

Mode doesn't depend on the value, so removing an outlier will not alter the mode.

The median may or may not change.

For instance the data set is:

1 2 3 3 3 3 99

Removing the outlier will not alter the median in this case

Since removing the outlier changes the sum drastically, mean also changes
