Every bar chart for discrete data must have: (1) equal width bars, (2) equal gaps between bars, (3) a vertical frequency axis starting at 0 with a uniform scale, and (4) clear labels on both axes.
In a dual (comparative) bar chart, two bars are drawn side-by-side for each category with a key. In a composite (stacked) bar chart, sub-categories are stacked on top of each other, so subtract the bottom reading from the top reading to find the upper section’s frequency.
Example 1: The bar chart shows pupils’ favourite sports: Football = 12, Tennis = 7, Rugby = 5, Swimming = 10. Find (a) total pupils & (b) how many more chose Football than Tennis.
(a) Total: 12 + 7 + 5 + 10 = 34 pupils
(b) Difference: 12 − 7 = 5 more pupils
Example 2: The dual bar chart shows club attendance (Drama: 6B, 9G; Music: 8B, 7G; Coding: 11B, 5G). Find total girls & greatest difference.
• Total girls: 9 + 7 + 5 = 21 girls
• Greatest difference:Coding (11 − 5 = 6, vs Drama 3, Music 1)
