• Pie Chart/Circle Graph


  -Shows how a whole is divided into parts. The parts must total 100%

  -Uses a circle divided into fractions to show idea. Three parts of the cirle graph must be present to be complete
• Pie Chart/Circle Graph

  • Three parts of the circle graph must be present to be complete: Title, Key, Circle
• Line Graph


  Used to represent changes in data over a period. Data are represented by points and are joined by line segments. The horizontal axis is used as the time axis and the vertical axis is used to show the changes in other quantity.
• Line Graph


  • Five parts of the line graph must be present to be complete: Title, Label, Scale, Points, Line
• Bar Graph


  A graph which uses horizontal or vertical bars to represent data. It allows us to compare groups of data and make quick generalizations about the data by examining the length of the bars.
• Histogram


  -A bar graph that shows the frequency of data that occur within a certain interval. The bars are always vertical, the width of each bar is based upon the size of the interval it represents, and there are no gaps between adjacent bars.

  -special kind of bar graph that uses data shown as numbers in order.
• Histogram


  • Four parts of the histogram must be present to be complete: Title, Scale, Labels, Bar
• General Rules in Making Charts/Graphs

  • Label axes
  • Include units
  • Keep your geometry in check
  • Include your sources
  • Consider your audience
