Python statistics.median_grouped() Method
Python statistics ModulePython statistics.median_grouped()Used to calculate the grouped median of a given grouped data set.
Syntax
The syntax of the statistics.median_grouped() method is as follows:
statistics.median_grouped(data, interval=1)
Parameter Description:
- data-- An iterable object containing grouped data, such as a list or tuple.
- interval-- An optional parameter representing the interval width of the grouped data, default is 1.
Return Value
The function calculates and returns the grouped median as a result based on the given grouped data set.
Example
The following example demonstrates the use of the median_grouped() function:
Example
data = [10, 20, 30, 40]
interval = 10
median = statistics.median_grouped(data, interval)
print(median)
Output result:
25.0
In the above example, the given grouped data set is [10, 20, 30, 40], and the interval width for each data point is 10. Using the median_grouped() method, the grouped median is calculated to be 25.0.
The median_grouped() method is used for handling large data sets where data is grouped into continuous intervals rather than listing each data point. It estimates the median of the entire data set by calculating the median of the grouped data set.
