Hướng dẫn is there a median function in python? - có một chức năng trung bình trong python không?

Python là một ngôn ngữ rất phổ biến khi 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 giá trị trung bình (), trung bình (), mode (), v.v. Ưu điểm lớn nhất của việc sử dụng hàm trung bình () là danh sách dữ liệu không cần phải được sắp xếp trước khi được gửi làm tham số đến hàm trung bình (). nửa dưới. Đối với một bộ dữ liệu, nó có thể được coi là giá trị trung bình. Trung bình là thước đo xu hướng trung tâm của các thuộc tính của tập dữ liệu trong thống kê và lý thuyết xác suất. Trung bình có một lợi thế rất lớn so với trung bình, đó là giá trị trung bình không bị sai lệch quá nhiều bởi các giá trị cực lớn hoặc nhỏ. Giá trị trung bình được chứa trong tập dữ liệu của các giá trị được cung cấp hoặc nó không bị ảnh hưởng quá nhiều so với dữ liệu được cung cấp. Giá trị trung bình là giá trị trung bình của hai yếu tố giữa. & NBSP;
median() function in the statistics module can be used to calculate median value from an unsorted data-list. The biggest advantage of using median() function is that the data-list does not need to be sorted before being sent as parameter to the median() function.
Median is the value that separates the higher half of a data sample or probability distribution from the lower half. For a dataset, it may be thought of as the middle value. The median is the measure of the central tendency of the properties of a data-set in statistics and probability theory. Median has a very big advantage over Mean, which is the median value is not skewed so much by extremely large or small values. The median value is either contained in the data-set of values provided or it doesn’t sway too much from the data provided.
For odd set of elements, the median value is the middle one.
For even set of elements, the median value is the mean of two middle elements.

Median can be represented by the following formula :

Cú pháp: các tham số trung bình ([[data-set]): & nbsp; Khi có thể vượt qua trống rỗng hoặc khi danh sách là null. & nbsp; & nbsp; median( [data-set] )
Parameters :
[data-set] : List or tuple or an iterable with a set of numeric values
Returns : Return the median (middle value) of the iterable containing the data
Exceptions : StatisticsError is raised when iterable passed is empty or when list is null.

Applications :
For practical applications, different measures of dispersion and population tendency are compared on the basis of how well the corresponding population values can be estimated. For example, a comparison shows that the sample mean is more statistically efficient than the sample median when the data is uncontaminated by data from heavily-tailed data distribution or from mixtures of data distribution, but less efficient otherwise and that the efficiency of the sample median is higher than that for a wide range of distributions. To be more specific, the median has 64% efficiency compared to minimum-variance-mean ( for large normal samples ).
