Study Notes

Econometrics - Definition and Scope

  • Econometrics utilizes statistical and mathematical techniques to analyze economic data.
  • Aims to prove or disprove economic propositions and models.
  • Involves quantitative analysis of economic phenomena based on theory, observation, and inference.
  • Blends economic theory, mathematical economics, economic statistics, and mathematical statistics.

Reasons for Studying Econometrics

  • Provides numerical estimates to qualitative economic theory.
  • Empirically verifies economic theory, often using mathematical equations formulated by mathematical economists.
  • Utilizes data collected by economic statisticians to test economic theories.
  • Requires specialized methods due to the unique nature of economic data, often not generated through controlled experiments.

Levels of Measurement

  • Nominal Level:

    • Categorizes data without ranking.
    • Categories are mutually exclusive and exhaustive.
    • Example: Gender (Male, Female, Other), Type of Fruit (Apple, Banana, Orange).
    • Assigned numbers lack mathematical meaning, only serve as identifiers.
  • Ordinal Level:

    • Categorizes data with a clear ranking.
    • Intervals between ranks are not necessarily equal or known.
    • Example: Class Rank (1st place, 2nd place, 3rd place), Satisfaction Level (Very Unsatisfied, Unsatisfied, Neutral, Satisfied, Very Satisfied).
  • Interval Level:

    • Ranks data with equal intervals between categories.
    • Zero point is arbitrary, not absolute.
    • Example: Temperature in Celsius or Fahrenheit.
  • Ratio Level:

    • Ranks data with equal intervals between categories.
    • Has an absolute zero point.
    • Example: Height, Weight, Income.
