    Answer:

Median number is the middle number in a sorted list. If a list has even number, then the median value is the average of two middle numbers. To find the median number, you need to

  1. Sort the list by size, e.g. [1, 2, 3], or [1, 2, 3, 4].
  2. For a list with odd number, find the middle number, e.g. [1, 2, 3] => 2 is the median number.
  3. For a list with even number, average the two middle number, e.g. [1, 2, 3, 4] => (2 + 3) / 2 = 2.5 is the median number.
