Python statistics.median() Method

❮ Statistic Methods


Calculate the median (middle value) of the given data:

# Import statistics Library
import statistics

# Calculate middle values
print(statistics.median([1, 3, 5, 7, 9, 11, 13]))
print(statistics.median([1, 3, 5, 7, 9, 11]))
print(statistics.median([-11, 5.5, -3.4, 7.1, -9, 22]))

Definition and Usage

The statistics.median() method calculates the median (middle value) of the given data set. This method also sorts the data in ascending order before calculating the median.

Tip: The mathematical formula for Median is: Median = {(n + 1) / 2}th value, where n is the number of values in a set of data. In order to calculate the median, the data must first be sorted in ascending order. The median is the number in the middle.

Note: If the number of data values is odd, it returns the exact middle value. If the number of data values is even, it returns the average of the two middle values.



Parameter Values

Parameter Description
data Required. The data values to be used (can be any sequence, list or iterator)

Note: If data is empty, it returns a StatisticsError.

Technical Details

Return Value: A float value, representing the median (middle value) of the given data
Python Version: 3.4
