POSITION MEASURES

POSITION MEASURES

1. These are measures that account for a certain position in the distribution of the data. The objective of this type of measure is to summarize in a single number the position of the data distribution.

2. Ungrouped data

   • Cuartiles
     • The three values of the variable of a distribution that divide it into four equal parts, i.e. 25%, 60% and 75%.
       • Deciles
         • They represent a position that divides the data set into 10 equal parts, grouping them in 10,20,30 ... and 90 percent.
   • Quintiles
     • They represent a position that divides the data set in 5 equal parts grouping them in 20,40,60 and 80 percent, which are represented by k1,k2,k3,k4.
       • Percentiles
         • They are the calculation of a position, which is used to determine the data value below which the required percentage is found.

3. Grouped data

   • Cuartiles
     • Divide los datos en 4 partes, esto nos permite determinar la dispersión y la tendencia central de los datos
   • Quintiles
     • Los quintiles son un conjunto de datos en lo cual lo podremos aplicar tanto para datos agrupado como para datos no agrupados
