Hướng dẫn how to find mean in python - cách tìm ý nghĩa trong python

Điều kiện tiên quyết: Giới thiệu về các chức năng thống kê là một ngôn ngữ rất phổ biến khi nói đến phân tích dữ liệu và thống kê. May mắn thay, Python3 cung cấp mô -đun thống kê, đi kèm với các hàm rất hữu ích như trung bình (), trung bình (), mode (), vv () hàm có thể được sử dụng để tính trung bình/trung bình của một danh sách số nhất định. Nó trả về giá trị trung bình của tập dữ liệu được truyền dưới dạng tham số. Giá trị trung bình là tổng dữ liệu chia cho số lượng điểm dữ liệu. Đây là thước đo vị trí trung tâm của dữ liệu trong một tập hợp các giá trị khác nhau trong phạm vi. Trong Python, chúng ta thường làm điều này bằng cách chia tổng số các số đã cho với số lượng số hiện tại. & NBSP; & nbsp;
Python is a very popular language when it comes to data analysis and statistics. Luckily, Python3 provide statistics module, which comes with very useful functions like mean(), median(), mode() etc.
mean() function can be used to calculate mean/average of a given list of numbers. It returns mean of the data set passed as parameters.
Arithmetic mean is the sum of data divided by the number of data-points. It is a measure of the central location of data in a set of values which vary in range. In Python, we usually do this by dividing the sum of given numbers with the count of number present. 
 

Given set of numbers : [n1, n2, n3, n5, n6]

Sum of data-set = (n1 + n2 + n3 + n4 + n5)
Number of data produced = 5

Average or arithmetic mean  = (n1 + n2 + n3 + n4 + n5) / 5

Cú pháp: trung bình ([data-set]) tham số: & nbsp; Các giá trị số được truyền dưới dạng tham số. & nbsp; & nbsp;: mean([data-set])
Parameters : 
[data-set] : List or tuple of a set of numbers.
Returns : Sample arithmetic mean of the provided data-set.
Exceptions : 
TypeError when anything other than numeric values are passed as parameter.

Applications : 
Mean/Arithmetic average is one of the very important function, while working with statistics and large values. So, with the function like mean(), trending and featured values can be extracted from the large data sets.
