If the height of a student is picked at random, the picked number has a higher chance to be closer to the median height than being classified as very tall or very short. For example, the height of the students in a school tends to follow a normal distribution around the median height. However, the pool of numbers may follow a specific distribution.
The pool of numbers is almost always independent from each other. A random number is a number chosen from a pool of limited or unlimited numbers that has no discernible pattern for prediction.
