Histogram is essentially a way of describing a group of items by the identifying how many of each type are in the group.


E.g. we can describe all the students in a classroom either by listing all their names:

  1. Susan
  2. Bob
  3. Karen
  4. Peter
  5. Sally


Or by saying that there are 3 girls and 2 boys. The description of the classroom as 3 girls and 2 boys is called a histogram.


It becomes trickier to count if the items in a group are real numbers. E.g.

  1. 1.1
  2. 1.3
  3. 2.4
  4. 5.4
  5. 3.2
  6. 1.4
  7. 8.9


We can describe the group as follows. There are 3 numbers between 1 and 2; there is 1 number between 2 and 3; there is 1 number between 5 and 6; and there is one number between 8 and 9.


I hope you get the idea.
