SF:Dispersion Graphs

• Dispersion graphs are used to show how far data are dispersed or clustered (e.g. the depth of earthquake foci at different types of tectonic plate margins). With a completed dispersion graph, it's possible to apply statistical skills to find:

  • The range (span of all the data)
  • The median (middle value)
  • The quartiles
  • The inter-quartile range
