Class 6 Maths Chapter 4 PDF: Data Handling and Presentation (Ganita Prakash)

Class 6 Maths Chapter 4, Data Handling and Presentation, teaches how to collect, organise and interpret real-world data using frequency tables with tally marks, scaled pictographs, vertical and horizontal bar graphs, and accurate infographics.

What Class 6 Mathematics Chapter 4 Covers

4.1–4.2 Collecting Data, Tally Marks & Pictographs organises raw observations into frequency tables using groups of five tally marks (4.1) and reads and draws pictographs by choosing an appropriate scale (such as 1 symbol = 5 or 10 items) to handle large frequencies cleanly (4.2).

4.3–4.5 Bar Graphs, Choosing Scales & Infographics interprets and constructs equally spaced vertical and horizontal bar graphs by selecting a suitable unit-length scale (1 unit = 1, 10, 50, 100 or 1000) (4.3–4.4), and examines visual aesthetics and how misleadingly scaled infographics can distort comparisons (4.5).

FAQ

Why is choosing a scale important when drawing a pictograph or bar graph?
When data values are large (such as hundreds or thousands), choosing a suitable scale (e.g., 1 symbol = 100 students or 1 unit length = 50 vehicles) allows the graph to fit neatly on the page while remaining easy to read and compare.

What are the key rules for drawing an accurate bar graph?
All bars must have uniform width, equal spacing between consecutive bars, and heights/lengths strictly proportional to the data values according to a clearly stated unit scale starting from 0.
