Title: Bar Graphs, Histograms, Line Graphs

Bar Graphs, Histograms, Line Graphs
  • Arizona State Standard Solve problems by
    selecting, constructing, interpreting, and
    calculating with displays of data. S2C1PO1

Objective
  • I will be able to use a bar graph to represent
    data.
  • I will be able to read and construct histograms.
  • I will be able to use a line graph to represent
    data.

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

Line Graphs
  • Line graphs show trends over intervals of time.
  • Line graphs can have one line or several lines.
