  19. SCIENTIFIC NOTATION Practice of Scientific Notation: 84 x 10-6 is scientific notation for _________ 84 x 10-6 0.000084 0.000084 The -6 represents the 6 times the decimal moves to the left from behind the 84.

  20. SCIENTIFIC NOTATION Practice of Scientific Notation: 9 x 10-8 is scientific notation for ____________ 9 x 10-8 0.000000009 0.00000009 The -8 represents the 8 times the decimal moves to the left from behind the 9.

  21. GRAPHING Graphing • Purpose: Visual display of information.

  22. 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.

  23. 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.

  24. GRAPHING TITLE UNITS KEY NEATNESS VARIABLES UNITS VARIABLES

  25. GRAPHING TITLE Favorite Colors of Students per Class Hour KEY NEATNESS VARIABLES Number of Students UNITS VARIABLES

  26. GRAPHING TITLE VARIABLES (teams identified on graph) KEY (colors labeled in graph) NEATNESS UNITS (percent labeled in graph)
