Position measurements

Position measurements

1. are measures that allow us to divide the data set into equal percentage parts

2. Classification

   • Non-central position measurements
     • Are the quantiles, which perform a series of equal divisions in the ordered distribution of the data, reflecting the upper, middle and lower values
       • The most common are
         • Quantile: are the three values ​​of the variable that divide an ordered data set into four equal parts
         • Deciles: any of the values ​​that divide an ordered data set into ten equal parts
         • Percentile: once the data is ordered from highest to lowest the value of the variable below which a given percentage of observations of a group is found.

3. Central position measurements

   • It allows us to summarize the distribution of the data in a single central value
     • half
       • most recognizable size
     • median
       • are three central measures that indicate a weighted average
     • Fashion
       • most frequent values
