Python Median ():
With the Python Statistics module, you can find the mean -median-mode-in-python-without-libraries/">median, or mean value, of a data set. The Python mean -median-mode-in-python-without-libraries/">median () function allows you to calculate the mean -median-mode-in-python-without-libraries/">median of any data set without sorting the list first.

When working with numbers in Python, you may want to calculate the mean -median-mode-in-python-without-libraries/">median of a list of numbers . For example, suppose you are creating a program to obtain information about the age of students in a grade four class. You may want to calculate the average age of the students.

This is where the statistics.mean -median-mode-in-python-without-libraries/">median () function comes in. The statistics.mean -median-mode-in-python-without-libraries/">median () function is part of the Python module statistics and allows you to find the mean -median-mode-in-python-without-libraries/">median of a list of values.

 This tutorial will explain how to use statistic .mean -median-mode-in-python-without-libraries/">median () method. We will also look at an example of statistics.mean -median-mode-in-python-without-libraries/">median () in action and analyze, line by line, how the method works.
 This tutorial will explain how to use the statistical method .mean -median-mode-in-python-without-libraries/">median (). We’ll also take a look at an example of statistics.mean -median-mode-in-python-without-libraries/">median () in action and analyze how the method works.
  Python Median
In statistics, the mean -median-mode-in-python-without-libraries/">median is the medium value in an ordered list of numbers. For example, for a dataset with the numbers 9, 3, 6, 1, and 4, the mean -median-mode-in-python-without-libraries/">median is 4.
 When parsing and describing a dataset, the mean -median-mode-in-python-without-libraries/">median is often used with  mean , standard deviation, and other statistical calculations.
 In Python, the statistics.mean -median-mode-in-python-without-libraries/">median () function is used to calculate the mean -median-mode-in-python-without-libraries/">median value of a dataset.

 statistics. mean -median-mode-in-python-without-libraries/">median () is part of the statistics for  Python module . It includes a number of functions for statistical analysis. First, import the statistics module with this code:
 We can now use the mean -median-mode-in-python-without-libraries/">median () function. Here is the syntax of the statistics.mean -median-mode-in-python-without-libraries/">median () method:
 The mean -median-mode-in-python-without-libraries/">median () method accepts one parameter: the list of data.

 When you call the mean -median-mode-in-python-without-libraries/">median () method, it will sort a list of values ‚Äã‚Äãand find its mean value.If the number of data points is odd, the central data point. If the number is even, the mean -median-mode-in-python-without-libraries/">median is the midpoint between the two central values.
  Python Median Example
Let’s take an example. Suppose we build a program that compute the age of all students in a fourth year class to know their age distribution. We want to use mean -median-mode-in-python-without-libraries/">median () to find out the average age of the class. 
 We could use this code:
 Our program returns:
 9.5
 This is the average age of the students.
 Let’s break down our code. On the first line, we import the statistics module to access the mean -median-mode-in-python-without-libraries/">median () method in our code. So, let’s define a list. The list is called student_ages . Stores the ages of all students.
 Next, we use mean -median-mode-in-python-without-libraries/">median () and pass the student_ages variable to calculate the average age. We assign the returned value to the mean -median-mode-in-python-without-libraries/">median_age variable. Then we use print () to print the value of mean -median-mode-in-python-without-libraries/">median_age to the console.
 When working with mean -median-mode-in-python-without-libraries/">median (), the list you use must have at least one value. If you pass an empty list via the mean -median-mode-in-python-without-libraries/">median () method, you get this error:
  Median of a tuple
You can also use the mean -median-mode-in-python-without-libraries/">median method to find the mean -median-mode-in-python-without-libraries/">median of a Tuple Python . A tuple is an ordered and immutable data type. This mean s that it is useful when you want to store similar data that will not change over time. Tuples are declared as a list of values ‚Äã‚Äãseparated by commas and surrounded by braces.

 Suppose our student age dataset is stored as a tuple rather than a listing. If we wanted to calculate the average age of fourth graders, we could do so using the mean -median-mode-in-python-without-libraries/">median () method. Here is the code we would use to calculate the mean -median-mode-in-python-without-libraries/">median of our tuple:
 Our code returns: 9.5 .
 The mean -median-mode-in-python-without-libraries/">median is the same, but instead of storing our data in a list, it’s stored in a tuple. This is obvious because our data is in parentheses (() ) instead of brackets ([]).
  Conclusion
You can use the statistics.mean -median-mode-in-python-without-libraries/">median () method to calculate the mean -median-mode-in-python-without-libraries/">median of a dataset. Using examples, this tutorial demonstrated how to use the statistics.mean -median-mode-in-python-without-libraries/">median () method in Python to calculate the average value of a list and a tuple.
 You now know that you should start using the statistics.mean -median-mode-in-python-without-libraries/">median () method like a professional Python developer!
