    If you add -600 to the list and you sort it, you'll get -600, 1, 2, 3, 4, 5, 6, 101, 102, 103, 104, 105 what's the mean and median now?

    You already have the answer, but here's why it's the mean: When adding -600 to the list, the median goes from 6 to 5.5 When adding -600 to the list, the mean goes from 48.727 to -5.3333 So we can see that the mean changes the most of the two.

    In general, adding a very large outlier will greatly affect the mean.
