An Introduction to Graph Types

• Some Graph Types
  • Pie Graphs
  • Bar/Column Graphs
  • Scatter Diagram - what to look for - pattern
  • Line Graph - what to look for
    • axes (qualitative vs. quantitative)
    • slope (direction of change)
  • Linear relationships (constant slope)
    • turning points (maximum-minimum)
  • Time-Series Graph
    • decomposition / cycles - trends
  • Multi-dimensional Relationships
    • 3-D graph
    • Contour Lines

• Some limitations of graphs?
  • Correlation Vs Causality
  • Scale distortion
