Bar charts present data much like graphs so many of the rules for graphs apply to bar charts.
• When making comparisons, try to group things together when possible.
o For example, in the above example we can say: “The students can be divided into two groups, UK students and non-UK students…”
• Then compare the two groups:
o For example, you could say: “Across all categories of study, UK students are more than double any of the non-UK students…”
• Then you can try to identify some specific features within the groups.
o For example: “For UK students, Arts subjects are most popular…”
• Or you can identify similarities between different groups;
o For example: “Arts subjects are most popular with British and French students, while engineering subjects tended to be more popular with German and Dutch students…”
• Although the data displayed was collected in the past, you can either the simple present or simple past to describe the information. For example:
o Simple past: “As we can see the number of cars increased/rose/decreased/shrank/contracted over time…”
o Simple present: “it is obvious that over time the number of cars increases/rises/decreases/shrinks/contracts…”
