GRAPHING Graphing • Purpose: Visual display of information.
GRAPHING Line Graphs • Used to show how data changes over time. Bar Graphs • Used for comparing information by counting. Circle or Pie Graphs • Used to show parts of whole.
GRAPHING 5 Essentials of Graphs • Neatness • Title: A brief way to describe the content of the graph. • Variables: Words used to describe what information is being collected. • Units: Words or symbols that identify how the information was measured. • Keys: Explains different colors or symbols on the graph.
