Dispersion measures

1. Concept

   • They are a set of variables that calculate they distribucion of they data un the analysis formulas and their degree of variability.

2. Range

   • Concept
     • Measures the width of they data series verween the highest and the lowest vale.
   • Formula

3. Variance

   • Concept
     • Is the arithmetic mean calculate for the squares of they difference.
   • Formula

4. Standard deviation

   • Concept
     • Corresponds to the squares root of they variance
   • Formula

5. Coefficient of variation

   • Concept
     • Relationship verween the standard deviation and the mean
   • Formula
