They are values or parameters that represent the entire population.
Media.
Also called average.
It refers to a measure in a sample or
in the population, and tries to measure
fair equitable, hope.
Quantiles.
Quartiles.
The quartiles are the three values of the
variable that divides a sorted data set in four
equal parts. Q1, Q2, Q3 determine the values
corresponding to 25%, 50% and to 75% of the
data. Q2 matches with the median.
Deciles.
The deciles are the nine values that divide the
data series into ten equal parts, the deciles give
the values corresponding to 10%, at 20% and
90% of the data. D5 matches the median.
Percentiles.
The percentiles are the 99 values
that divide the data series by 100
equal parts. The percentiles give
the values corresponding to 1%,
2% and 99% of the data.
Quintiles.
A quintile is one fifth of a statistical
population sorted from smallest to largest
some feature of it. Divide the population
into five equal parts, each contains 20% of
the data population. There are 4 quintiles
that they are denoted by Q1, Q2, Q3, Q4.
Median
It is the central point of a data distribution.
*In ungrouped data the median is
calculated by simple observation.
*The data must be ordered *If n is
odd median is the central data.
*Without is even the median is the
average of the core data.
Moda.
In a distribution of data, it is the data
that is repeated the most, if the data
they are not grouped the fashion is
calculated by simple observation.
In the same way in a distribution of
data may not exist mode and called
AMODAL.
