what is an index
What is an Index?
  • A way to Quantify the Unquantifiable
examples of indices
Examples of Indices
  • From everyday Life?
    • Ranking movies, ranking hotels, ranking restaurants, best schools, best cities
  • From schooling?
    • SAT, your GPA, grading scales in classes
  • From geography?
    • Palmer Drought Severity index, sand mobility index, soil development index

Selecting Index Elements

  • Out of how many?
    • A possible score of 10? 100?
  • Elements:
    • What scale?
      • 1 - 10? 1-5? 0-3?
    • Do you want to weight elements
    • What are you missing?
  • How to score

    • 2 obvious
    • 3 dominant
analyst discretion
Analyst Discretion
  • May be concerned about specific environmental factors
  • One parameter might be extremely dominant
  • Choose a multiplication factor for any of the parameters
  • Example:
    • Extreme fissures
