Median Formula Class 9
Median is the middle value of the given number of observations, that divides it into exactly two parts. The concept of median holds great importance in analyzing and interpreting data present around us. Therefore, it is necessary that students have a clear understanding of all formulas and concepts covered in this topic. To make memorization of median formula class 9 easy this article provides a list of important formulas with relevant examples.
List of Median Formula Class 9
Students can refer to the list of formulas associated with median formula class 9 to learn and understand some important concepts.
 Mean is calculated by adding all the values of the given observations and then dividing them by the total number of observations.
 Median is the value of the observation that is situated in the middle. It can be expressed as [(n + 1)/2]th term
 Median Formula for an Odd number of observations: The median formula of a given set of numbers, say 'n' odd number of observations, can be expressed as:
Median = [(n/2)th term + ((n/2) + 1)th term]/2
 Median Formula for an Even number of observations: The median formula of a given set of even numbers, can be expressed as:
Median = [(n + 1)/2]th term
 Mode is the observation that occurs frequently.
Applications of Median Formula Class 9
To find the central tendency of the distribution of data, median is an excellent measure. Thus the use of median formulas is prominent in various important calculations. Here are some examples of the applications of median formula class 9:
 Median formula class 9 is applied to get an idea of the average salary of a country or city. It's usually the median that is used as a measure.
 These formulas are helpful in defining the accurate value for various benchmarks such as calculating the poverty line.
 Owing to the valuable contribution of statistical data in making important management decisions the use of median formula class 9 is prominent in business calculations.
Median Formula Class 9 Examples
Example 1: In class tenth, there are ten kids with the marks scored as below what is the average marks and Median marks scored in the class
NAME 
MARKS 

Ram 
90 
Shyam 
80 
Mohan 
15 
Rani 
60 
Jingle 
100 
Damru 
10 
Rita 
0 
Neha 
60 
Akshara 
100 
Kiara 
40 
Solution:
Average Marks = 90 + 80 + 15 + 60 +100 +10 + 0 +60 +100 +40 /10
= 55.5
To find Median first we need to arrange data in ascending order, i.e., 0, 10, 15, 40, 60, 60, 80, 90, 100, 100
Since the middle of this distribution is 60.
So, the Median is 60.
Example 2: Find the Median of the below distribution
8, 14, 23, 35, 45, 76,89, 90, 120, 200
Solution : Number of data points in the distribution = 10
Sorting the distribution = 8, 14, 23, 35, 45, 76, 89, 90, 120, 200
Locating the two points in middle = 45 and 76
Average of two middata points = 45+76/2
Median = 60.5
