If you are looking out for summarizing your data, you would probably start by calculating the mean (or average), the median, and the mode of the data. Finding the centralized data (known as central te, How to Find Mean Mode and Median in Python for Data

[2,3,4], the median is 3 [2,3], the median is (2 + 3) / 2 = 2.5 Design a data structure that supports the following two operations: void addNum(int num) - Add a integer number from the data stream to the data structure. double findMedian() - Return the median of all eleme...
Wir können die Formel zum Finden des Medians von Daten auch mit Python anwenden und unsere benutzerdefinierte Funktion erstellen. Ein Beispiel, lst=[7,8,9,5,1,2,2,3,4,5]defmedian(l):half=len(l)//2l.sort()ifnotlen(l)%2:return(l[half-1]+l[half])/2.0returnl[half]print(medi...
