# 中位数 英文:median # 对于有限的数集,可以通过把所有观察值高低排序后找出正中间的一个作为中位数。 # 如果观察值有偶数个,通常取最中间的两个数值的平均数作为中位数。 def get_median(data): data = sorted(data) size = len(data) if size % 2 == 0: # 判断列表长度为偶数 median = (data[...

Python median(): With the Python statistics module, you can find the median, or middle value, of a data set. The Python median() function allows you to calculate the median of any data set without first sorting the list. When you’re working with numbers in Python, you may want to ...
