dispersion measurements

dispersion measurements

1. Amplitude or range between the 10th and 90th percentile (RP)

   • Studying the dispersion between these percentiles, there are no advantages to making rp a popular variability measure and in fact it is rarely used. This is a little more stable than the range and is easier to calculate

2. Rango intercuantil (RQ)

   • Higher than the range where it calculates between the first and third quartile and two extremes of a quarter of the sample are eliminated, developing the majority of scores that are grouped in the remaining proposition.

3. Ranges

   • is evidentr
     • difference between the lowest and highest values ​​in the sample
     • see the highest and lowest values ​​of the group
   • disadvantages and advantages
     • The difference between the largest numbers and minor numbers of a group of scores is evident or by identifying both numbers

4. are

   • They are a set of variables that are used in statistics that help calculate the way the data is distributed in the analysis formulas anf variety based on a refered the degrees once value.

5. varianton ranger
