In many real-life situations, it is helpful to describe data by a single number that is most representative of the entire collection of numbers. Three ways of characterizing any data distribution are:

  • Measures of Central Tendency.
    Describe the center point of a data set with a single value.

  • Measures of Dispersion.
    Describe how far individual data values have strayed from the mean.

  • Measures of Skewness and Kurtosis.
    Describe the degree of asymmetry and peakedness of a distribution, usually taken relative to a normal distribution.
You need to know that some measures of central tendency and variability are inappropiate for qualitative variables.
