RS Aggarwal Solutions Class 10 Maths Chapter 9 Mean Mode and Median – Overview
Important Concepts Of RS Aggarwal Solutions Class 10 Maths Chapter 9
- Mean
The value of a set of data is the average value of that data, and it is measured by the following formula:
x‾ = ∑x/n
Where,
n = number of occurrences
You may use the direct method, assumed mean method, or step-deviation method to find the mean value of a set of data.
- Mode
It is the observation or value in a set of data that occurs the most frequently in that set. The following is the formula to be used when trying to find the mode:
Mode = {l+(f1-f0)/(2f1-f0-f2)} x h
Where,
L = lower limit of the modal class
h = size of the class interval
f1= frequency of the modal class
f0= frequency of the class above the modal class
f2= frequency of the class below the modal class
- Median
You will get the value of the data which lies middle-most in the set of data through the Median, and the formula for it is
Median = (n+1/2)th
occurrence where n = number of occurrences
Different kinds of data sets (i.e. individual, discrete, and continuous series) have their own variations of the basic formulae to find the mean, median, and mode.

x‾ = ∑x/n
Where,
x¯ = mean value
∑x = sum of all values
n = number of occurrences
What is a Mode?
It is the observation or value in a set of data that occurs the most frequently in that set. The following is the formula to be used when trying to find the mode:
Mode = {l+(f1-f0)/(2f1-f0-f2)} x h
