NCERT Class 9 Statistics | Bar Graph, Histogram & Data Representation Made Easy

In this Class 9 Maths session, we explain the core concepts of Statistics from NCERT Chapter 12. Students will learn how to represent data using Bar Graphs, construct Histograms accurately and understand the basics of data classification. Exercise 12.1 is solved step-by-step to support CBSE 2025 exam preparation. Topics Covered: • Introduction to Statistics • Types of data: primary and secondary • Bar Graph: construction and interpretation • Histogram: drawing, reading and real-life usage • Difference between bar graph and histogram • Frequency distribution table • NCERT Exercise 12.1 explained with examples Exam Tips: • Check class intervals carefully before drawing histograms. • For bar graphs, keep equal spacing between bars; for histograms, bars must touch. • Label axes neatly to score presentation marks. • Interpret graphs by comparing heights, class intervals and frequencies. • Practise all NCERT questions for strong exam performance. Learning Tips: • Use graph paper to practise drawing neat histograms. • Make a small chart comparing bar graph vs histogram. • Rewrite definitions in simple language for revision. • Work on real-life datasets to understand how graphs represent information.
