Bar graphs

दंड आलेख (बार ग्राफ)

In Class 9 Mathematics, this Statistics topic introduces students to bar graphs as a clear way to represent and compare categorical or discrete data. Students learn to read titles, axes, labels, scales, and frequencies; distinguish separate bars from continuous graphs; draw accurate graphs from tables; and interpret patterns, differences, and highest or lowest values. Practice focuses on choosing a suitable scale, plotting bars with correct widths and gaps, and answering data-based questions.
