I really don't get histograms. Please help?

In histrograms, you draw bars to consolidate data in your groupings. So if your groups involve responses of 1-3,4-6,7-9,10-12,13-15. You sum the number of responses in each group (the first group has 5), and draw a bar of uniform height 5 between 1 and 3.
