Introduction

Mean x-=Σfixi/Σfi

The median is the middle value of distribution; that is, the median is the variable’s value that divides it into two equal parts.
The variable’s mode is the value with the highest frequency.
The following relationship connects three central value measures: Mode=3 Median2 Mean.
Statistics is the discipline of organising and presenting data.
Statistics aid in planning businesses, economies, governments, and even individuals.
The sum of all observations divided by the number of observations is the arithmetic mean of a set of data.
The median of the data is the value of the middlemost observation obtained after arranging the data in ascending or descending order.
The most frequent value in the given data, i.e. the observation with the highest frequency, is called a mode of data.
In NCERT Class 10 Maths Statistics chapter, students will learn to calculate the mean, median, and mode from grouped data. Furthermore, they will also learn the concept of cumulative frequency, the cumulative frequency distribution, and how to draw cumulative frequency curves, called ‘ogives’. Students can find all the topics covered in NCERT Class 10 Maths Statistics chapter below:
We cannot determine the mode in a grouped frequency distribution using specified frequencies, but we can find a class with the highest frequency, known as the modal class. The mode is a value within the modal class, and its formula is as follows:
where l = lower limit of the modal class,
h = size of the class interval (assuming all class sizes to be equal),
f₁ = frequency of the modal class,
f₀= frequency of the class preceding the modal class,
f₂= frequency of the class succeeding the modal class.
