  18. What indicates a stronger correlation on a scatter graph?

    • Equal axis scales
    • Points widely spread
    • Points near line
    • Horizontal trend line

  19. Why can a strong statistical correlation not prove direct causation?

    • Third factors possible
    • Graphs have no scales
