Introduction to Data Handling
Data handling refers to the process of collecting, organizing, and representing data in a meaningful way. In everyday life, we come across data in many forms, such as marks in exams, number of students in a class, or daily temperatures.
Bar graphs are one of the simplest and most effective ways to represent such data visually.
In this chapter, students learn:
- What data is and how it is collected
- How to organize data in tables
- How to represent data using bar graphs
- How to interpret information from bar graphs
What is a Bar Graph?
A bar graph is a graphical representation of data using rectangular bars. The length or height of each bar represents the value of the data.
Key features of a bar graph include:
- Equal width bars
- Equal spacing between bars
- A clear scale
- Labels for axes
Bar graphs make it easy to compare different categories of data quickly.
Types of Data in Bar Graphs
In RD Sharma Class 6 Maths Chapter 23 Data Handling Bar Graphs, students work mainly with simple data sets such as:
- Number of students in different classes
- Marks obtained in subjects
- Sales of items over days
- Daily temperature records
Understanding these examples helps students relate mathematics to real-life situations.
