Measures of central tendency.
- 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 a distribution they can exist.
- 1 Moda:
Unimodal
2 Moda:
Bimodal 3
Moda:
polymodal
- In the same way in a distribution of
data may not exist mode and called
AMODAL.
