Data Handling and Presentation
About this chapter
Data Handling and Presentation is the fourth chapter of Class 6 Ganita Prakash. It starts with a simple question — what is the most popular game in our class? — and builds five core ideas. First, what counts as data: any collection of facts, numbers, measures or observations. Second, how to organise raw data using tally marks, frequency tables and ascending order. Third, how to read a pictograph, including those where one symbol stands for many items, and how to draw one by choosing a sensible scale. Fourth, how to read and draw a bar graph, choose the right scale, and compare categories at a glance. Fifth, the artistic and aesthetic side — column graphs, infographics, and how a fancy picture can sometimes mislead. CTET Paper 2 Mathematics tests this chapter through pictograph and bar-graph interpretation, scale questions, and pedagogy items on how a teacher introduces data through classroom surveys. The four tests — Practice 15, Quiz 15, Hard 15, Mastery 30 — cover all five ideas at the right depth.
