A measure of location is a value that divides a data set into equal percentages used to rank the
observations in a population or sample.
features
They allow you to divide a data set into equal percentages and are used to
rank the observations in a population or sample. The most common
measures of position are quartiles, deciles, and percentiles.
This is a number chosen to indicate the direction
of the data set and is useful for interpreting the
information as a percentage.
the types of measurements are:
deciles
is a measure of position that divides the frequency distribution into
ten equal parts starting from the first to the ninth. Deciles are
denoted by the letter Da
parameters
The location parameter has the function of determining the distribution along the line. their values
depend on the presence or absence of phenomena such as Asymmetry, non-normal data, coexistence

The main position parameters are:
Arimetic mean:
this is the most used position parameter because it summarizes A set of data in a single value that
provides the concept of location its entirety. center of gravity can also be considered distribution to

These measurements are primarily used to determine the
values in a data set that lie in a frequency distribution.
