Stacked bar graphs

संचित दंड आलेख

In Class 9 Mathematics, under Statistics, students learn how stacked bar graphs represent several related categories within one bar. They practise reading the scale and legend, identifying individual segments and overall totals, comparing groups, and interpreting patterns in data. The topic also develops skills in organising categorical information, constructing a clear stacked bar graph from a data table, and drawing conclusions while distinguishing between part-to-whole relationships and direct comparisons.
