Histograms & Frequency Polygons

• Constructing a Histogram

  • 1. Make a frequency table
  • 2. Make a scale of values, from lowest to highest
    • 1 2 3 4 5 6
  • 3. Make a box for each case above the value

• Do you see how histograms are constructed from frequency tables and grouped frequency tables? (using individual scores and intervals)

• Can you construct Frequency Polygons?
