  1. Now I'd like to ask you to find a median for me,
  2. but I'd also like to introduce a little twist.
  3. In the lecture, we said that the median is an element in the set, in the middle of the set.
  4. So if there's an even number, it can be 1 of 2 things.
  5. So I'd like you to give me one of those medians here.
  6. We'll call this the in data type of median.
  7. But the problem with it is it's not unique.
  8. Many people prefer to use a unique median,
  9. and to do that, they just take the simple mean of the acceptable answers for the in data method.
  10. Tell me the unique median over here.
