NCERT Class 6 Maths 2025 Chapter 4 C DATA HANDLING & PRESENTATION PAGES 79, 80, 81, 82, 83, 84 & 85 4.2 Pictographs A pictograph represents data through pictures of objects. It helps answer questions about data with just a quick glance. • Which mode of travel is used by the most number of students? • Which mode of travel is used by the least number of students? Example: Nand Kishor collected responses from the children of his middle school in Berasia regarding how often they slept at least 9 hours during the night. He prepared a pictograph from the data: Answer the following questions using the pictograph: 1. What is the number of children who always slept at least 9 hours at night? 2. How many children sometimes slept at least 9 hours at night? 3. How many children always slept less than 9 hours each night? Explain how you got your answer. Drawing a Pictograph If they want to show their data through a pictograph, where they also use one symbol for each student, as Lakhanpal did, what are the challenges they might face? What could be the problems faced in preparing such a pictograph, if the total number of students present in a class is 33 or 27? Pictographs are a nice visual and suggestive way to represent data. They represent data through pictures of objects. A scale or key (for example, : 1 student or : 5 students) is added to show what each symbol or picture represents. Each symbol or picture can represent one unit or multiple units. Figure it Out 1. The following pictograph shows the number of books borrowed by students, in a week, from the library of Middle School, Ginnori: a. On which day were the minimum number of books borrowed? b. What was the total number of books borrowed during the week? c. On which day were the maximum number of books borrowed? What may be the possible reason? 2. Magan Bhai sells kites at Jamnagar. Six shopkeepers from nearby villages come to purchase kites from him. The number of kites he sold to these six shopkeepers are given below — Prepare a pictograph using the symbol to represent 100 kites. Answer the following questions: a. How many symbols represent the kites that Rani purchased? b. Who purchased the maximum number of kites? c. Who purchased more kites, Jasmeet or Chaman? d. Rukhsana says Poonam Ben purchased more than double the number of kites that Rani purchased. Is she correct? Why?
