Position measures are those where you can divide the
data into two equal parts, called median, you can divide it into
four equal parts called quartiles, into ten equal parts
called deciles and in percentiles divided into 100 equal parts.
The median is a measure of position with respect to the data
central because it is divided into two parts (50%)
The position measurements are:
Definition of Position Measurements
• It is finding in a series of data or in a
frequency distribution specific values,
They also provide summary information on the
variable under study.
• They provide us with information about the series of data we are analyzing.
Also being a centralization measure such as
the median that represents 50% of the data because
divides the series or distribution into two parts
equals is considered a measure of position.
Percentiles
- The data is divided into 100 equal parts
• It is calculated from P1 to P99
Deciles
-The data is divided into 10 equal parts
• It is calculated from D1 to D9
Quartiles
-The data is divided into four equal parts
• Q1= 25%, Q2=50%, Q3=75%
• Position measures are quartiles, deciles
percentiles, used to find specific points
in ungrouped or grouped data that we are
driving in our investigation.
