The main problem with median is that it can be biased.
def median(lst):
n = len(lst)
if n < 1:
return None
if n % 2 == 1:
return sorted(lst)[n//2]
else:
return sum(sorted(lst)[n//2-1:n//2+1])/2
This is a function to find the median of a list. The median is the middle value in a sorted list. If there are an even number of values in the list, then the median is the average of the two middle values.
The first line defines the function and gives it the name “median”. The second line finds the length of the list and stores it in a variable called “n”. The third line checks to see if there are any values in the list. If not, it returns “None”. The fourth line checks to see if there are an odd number of values in the list. If so, it sorts the list and returns the value in the middle. The fifth line does the same thing as the fourth line, but for even numbers of values in the list. It sorts the list and returns the average of the two middle values.
Mediana
Mediana is a Python module that calculates the median of a data set.
Statistics
Statistics in Python can be used for a variety of purposes, including data analysis, forecasting, and scientific computing. In Python, statistical functions are provided by the pandas library. This library provides a number of statistical functions, including:
– Statistical operations such as mean, median, mode, standard deviation, and correlation
– Data frames that can be used for analysis or plotting
– Functions to generate random samples from a population
