MEASURES OF DISPERSION

MEASURES OF DISPERSION

1. They are numerical values ​​that measure the dispersion or variation between the data.

   • Small values ​​are those that are close to the average.
   • Large values ​​imply that the data is far from the average.
   • MAIN DISPERSION MEASURES
     • STANDARD DEVIATION
       • It is a type of average deviation of the values ​​with respect to the measurements.
     • INTERQUARTILE RANGE
       • They cover 50% of the total data and that are in the center, it is the difference between the third and first quartile
     • COEFFICIENT OF VARIATION
       • Describes the relative standard variation of the measure
     • RANGE
       • It is the difference between the maximum value and the minimum value.
     • VARIANCE

2. Variation: Amount of data that varies with each other

3. Less dispersion = more homogeneous

4. Less dispersion = less heterogeneous

5. May dispersion = less homogeneous
