  1. >> Range sometimes changes when we add new data to the data set. We could add a
  2. lot of data values here in the middle and it would really change the shape of
  3. our distribution. But it wouldn't change the range. Same here. So instead of a
  4. 187, we could have 190. We could keep adding values to the data set and the
  5. range would never change. But if we added a value out here higher than the
  6. maximum value or out here or even down here. It would change the range of our
  7. data set. We lose detail with the range because it's only based on two scores.
  8. And these scores are the most extreme in the distribution. These extreme values
  9. are likely not very representative of the rest of the distribution.
