Summary_Statistics

back to Statistical Theory -- Summarizing Statistical Data

The easiest way to approach this subject is to focus on what we have and what we want to achieve:

  • We have a set of observations which we want to summarize.
  • We want to communicate as much as possible as simply as possible.

    • Statisticians commonly try to describe the observations in

  • a measure of Central Tendency like the Arithmetic Mean, and
  • a measure of Statistical Dispersion like the Standard Deviation.
