2. Measures of dispersion

   • Examples
     • The most common measures of central tendency are the arithmetic mean, the median and the mode.
   • Utility
     • A central tendency can be calculated for either a finite set of values or for a theoretical distribution, such as the normal distribution.
   • is the extent to which a distribution is stretched or squeezed.
