  5. 9. Shows each data value as a dot above its location on a number line.
  6. 13. The distance between the minimum value and the maximum value.
  7. 14. The median of all data values that are to the left of the median (of the entire data set).
  8. 17. The median of all data values that are to the right of the median (of the entire data set).

  12. 18. If the right side of the graph is approximately a mirror image of the left side.
