  • Illustrating Data
    • Barcharts
      • -Categorical Data
      • -Gaps(same width) between bars
      • -Height of bar= FREQUENCY
      • -USED TO COMPARE FREQUENCIES OF DATA
      • e.g. Compound (subdivided), Multiple, Horizontal
    • Vetrical Line Charts
      • used to represent discrete data
      • gaps between lines
      • hieght of line= FREQUENCY
    • Pie Charts
      • categorical, discrete or grouped data
      • shows relationship of one part against the whole
      • Comparison - Area is proportional to the data
    • Histograms
      • continuous data
      • no gaps between bars
      • Area = proportional to frequency of each class
      • vertical axis = FREQUENCY DENSITY
