Histograms, Cumulative Frequency Plots

  • Graphs are used to identify a distribution’s center, spread, clusters of data, gaps in the data, and shape.

  • Histograms can be used with frequencies, relative frequencies, and densities.

  • If drawing a histogram by hand, there should be no gaps between the classes unless no observations are in that class.

  • Cumulative frequency plots are always non-increasing.
