Introduction to statistical characteristics

In order to answer the question:

How can we briefly describe a number of observations at large
(representing all the data without the need to communicate the data itself)?

descriptive statistics distinguish three different measures:

What number best represents the distribution of the values measured?

  • Measures of central tendency summarize the features of a distribution.
  • In addition to measures of central tendency, what other indicators are there for describing a distribution?

  • Measures of dispersion (spreads), summarize the variability of a distribution.
  • Which methods are there to compare two distributions?

  • Standardisation
  • On the following pages you will get an overview over the most commonly used statistical averages.
