The median of a set of data is the middlemost number or centre value in the set. The median is also the number that is halfway into the set. To find the median, the data should be arranged first in order of least to greatest or greatest to the least value.
The median formula class 10 represents the middle value when the data is arranged in ascending order. The middle value of the arranged set of numbers can be calculated by applying the median formula.
To find the median class, we have to find the cumulative frequencies of all the classes and n/2. After that, locate the class whose cumulative frequency is greater than (nearest to) n/2. The class is called the median class.
Median represents the middle value for any group. It is the point at which half the data is more and half the data is less. Median helps to represent a large number of data points with a single data point. Understand how to find median using examples.
The formula for the median of grouped data depends on the observations, the class size, the frequency, and the cumulative frequency. The formula to calculate the median (in class 10) is l + [ (n/2−c)/f] × h.
But in this concept of class 10th we will study how to find median of grouped data. The formula to find median of grouped data is. Median= l + { ( N 2) - c f f } × h. l= lower limit of the median class. N= ∑fi= sum of the frequencies. cf= cumulative frequency. f= frequency of the median class. h= Class size.
Calculate Median using following Formula M = L + ( n 2 – cf ) h f. Where, L is Lower limit of Median Class. n is Total frequency. cf is the cumulative frequency of the class preceding the Median Class.

5 days ago · Textbook Solutions. CBSE Notes. Introduction to Median. Median Definition. So let’s say for example in a tough exam, you and your friends performed very averagely. However, this one brainiac scored 100%. Now when you calculate the average marks of the class, it’s higher due to his score. But, this is not a fair representation of reality.
Jan 22, 2024 · MEDIAN: Median is a measure of central tendency that gives the value of the middle-most observation in the data. …where [l = Lower limit of median class; n = Number of observations; f = Frequency of median class; c.f. = Cumulative frequency of preceding class; h = Class size]
