Important Topics for RD Sharma Solutions for Class 8 Chapter 23: Data Handling I Classification and Tabulation of Data

Introduction

  1. Classification of Data: Data is classified or grouped in different categories on the basis of its kind, nature or format. The process of classification is done considering the application of the same.
  2. Tabulation of Data: Tabulation of data is done with an objective to depict the data systematically and hence, improve the process of summarising and analysis of the given data. Data can be tabulated only after the process of classification is complete.

Classification of Data

The given data is categorised under subheadings of different suitable classes as per the requirement of the question. The classes can be discrete as well as grouped in nature with a lower and upper limit of the class interval. These class intervals play a major role in the procedure of tabulation.

Tabular Representation

To tabulate a given set of data, we mention the class or class interval in one column, while in another parallel column, we mention the data belonging to that class or if the data is repetitive, we can use tally marks or frequency of the class to represent the number of repetitions.

The frequency distribution table can be of two types:

  1. Discrete frequency distribution table
  2. Continuous frequency distribution table.

The tabulated data can be used to calculate the mean, median and mode of a given set of data easily by using mathematical formulae.
