Visual Learning
Understanding a Bar Graph
A bar graph uses rectangular bars to compare quantities. The height or length of each bar represents the corresponding value.
Quick Notes
Remember These Points
- • Data means information collected for a purpose.
- • A table can organise data into rows and columns.
- • A pictograph represents data using pictures or symbols.
- • A bar graph represents quantities using rectangular bars.
- • A suitable scale should be selected when drawing a bar graph.
