Bar Graphs

• A bar graph uses vertical or horizontal bars to
  display numerical information.
• Bar graphs can be used to compare amounts.
• Choose an appropriate scale (with regular
  intervals).
• The bars should have the same width.

Histograms compare continuous data in intervals

• A histogram is a bar graph in which the bars
  represent equally spaced intervals of numbers
  (you must decide on your equal intervals).
• There are no spaces between the bars on the
  histogram.
• Make a frequency distribution use the totals to
  create the histogram
