Task 1 Academic — Bar Chart

Highest/lowest framing · grouping logic · percentage vs. absolute

Topic & Why It Matters

A bar chart tests your ability to compare categories clearly. Unlike a line graph, it often does not focus on change over time. Instead, you need to rank values, group similar bars, identify the largest and smallest figures, and choose enough detail to support the overview.

Candidates usually lose marks when they describe the bars one by one, ignore the unit, or mix percentage language with absolute-number language. A strong response reads like a guided comparison: the examiner can see the main pattern first, then the selected evidence that proves it.

Knowledge Points

Bars are about comparison first
A bar chart normally compares categories at one point in time or across a small number of groups. Your job is to show which items are highest, lowest, similar, or clearly different. Do not describe each bar in isolation.
Group before you write
Before writing, decide whether to group by category, by place, or by pattern. Good grouping creates natural body paragraphs and prevents a mechanical list of values.
Highest and lowest are anchor points
Examiners expect you to identify the extremes. Mention the largest and smallest values in the chart, then support the comparison with selected middle values where they help the reader understand the pattern.
Percentages and absolute figures behave differently
If the chart uses percentages, compare proportions: 'twice as high a share'. If it uses dollars, tonnes, or numbers of people, compare amounts: 'spent $40 more'. Never call an absolute value a percentage or a share.
Use approximate language when needed
Bar charts often use gridlines rather than exact labels. If a bar appears between two gridlines, write 'about', 'roughly', or 'approximately'. If the value is labelled, report it directly.
No causes, opinions, or predictions
Task 1 Academic asks for description only. Do not explain why one city spends more, predict future changes, or recommend policy. Stay inside the visual evidence.

Structure Template

Four paragraphs, about 160-175 words total. Decide your grouping before writing.

ParagraphTargetWhat to Write
Paragraph 1 — Introduction25–35 wordsParaphrase the chart title. Name the categories, groups, time frame, and unit. Keep this sentence factual and compact.
Paragraph 2 — Overview30–45 wordsState the broad pattern: which category dominates, which group is highest overall, and which value is lowest. Do not include specific figures here.
Paragraph 3 — Body A45–60 wordsDescribe the strongest group or category with exact values. Use comparisons such as 'slightly higher than', 'followed by', and 'respectively'.
Paragraph 4 — Body B40–55 wordsCover the remaining categories or exceptions. End with a sentence that links the detailed data back to the overview.
The golden rule: Do not move left to right automatically. First ask which bars belong together. Then build the body paragraphs around those groups.

Common Pitfalls

MistakeCorrection
Writing one sentence for every barGroup bars into patterns. For example, compare all food figures first, then transport and leisure, instead of moving city by city without a clear logic.
Putting numbers in the overviewThe overview should contain the main pattern only. Save exact values for body paragraphs.
Confusing percentages with amountsIf the unit is dollars, write 'households spent $170'. Do not write 'food accounted for $170' or 'the share was $170'.
Ignoring the lowest valueA strong overview usually mentions both ends of the scale. If the lowest figure is not named in the overview, include it clearly in a body paragraph.
Overusing dramatic languageStatic bar charts do not 'surge' or 'plummet' unless they show change over time. Use comparison language, not trend verbs, for one-year charts.

Model AnswerBand 7.5+ · 170 words

The bar chart compares average weekly household expenditure on food, transport, and leisure in four cities in 2023, measured in US dollars.

Overall, food was the largest spending category in every city, while leisure received the least money in London and Toronto. Sydney recorded the highest total outlay across the three categories, whereas Toronto had the lowest.

In detail, Sydney households spent $170 a week on food, slightly more than London at $160 and clearly above Tokyo and Toronto, at $140 and $130 respectively. Transport costs were highest in London, at $120, followed by Sydney at $100. By contrast, Tokyo and Toronto spent noticeably less on this category, at $80 and $90.

Leisure spending showed a different pattern. Sydney again led, with $130, while Tokyo allocated $110, making it the only city where leisure exceeded transport. London spent $90 on leisure, and Toronto had the lowest figure in the chart, at $75. Taken together, the data suggest stronger overall spending in Sydney and London than in the other two cities.

Annotated Commentary

Each paragraph is quoted, then broken down by examiner criteria. Notice how the overview selects the pattern and the body paragraphs prove it with exact values.

[ Paraphrase ]Paragraph 1 — Introduction
The bar chart compares average weekly household expenditure on food, transport, and leisure in four cities in 2023, measured in US dollars.
Lexical upgrade'compares' is more precise than 'shows' for a bar chart
Task framingNames the categories, cities, year, and unit in one compact sentence
Syntax change'measured in US dollars' moves the unit into a reduced clause
[ Thesis ]Paragraph 2 — Overview
Overall, food was the largest spending category in every city, while leisure received the least money in London and Toronto. Sydney recorded the highest total outlay across the three categories, whereas Toronto had the lowest.
Thesis (overview)Identifies the dominant category, lowest-pattern category, highest city, and lowest city
Cohesive device'while' and 'whereas' compare opposite patterns without adding numbers
Lexical upgrade'total outlay' avoids repeating 'spending'
Data selectionNo exact figures appear here, so the paragraph remains a true overview
[ Topic sentence ]Paragraph 3 — Body A
In detail, Sydney households spent $170 a week on food, slightly more than London at $160 and clearly above Tokyo and Toronto, at $140 and $130 respectively. Transport costs were highest in London, at $120, followed by Sydney at $100. By contrast, Tokyo and Toronto spent noticeably less on this category, at $80 and $90.
Topic sentenceBegins with the leading city and the most important category: Sydney's food spending
Cohesive device'followed by' creates a ranked sequence for transport
Complex grammar'slightly more than London at $160...' compresses comparison and data into one sentence
Lexical upgrade'noticeably less' is more controlled than 'much less' when the gap is moderate
Data accuracy'respectively' correctly links Tokyo with $140 and Toronto with $130
[ Contrast ]Paragraph 4 — Body B
Leisure spending showed a different pattern. Sydney again led, with $130, while Tokyo allocated $110, making it the only city where leisure exceeded transport. London spent $90 on leisure, and Toronto had the lowest figure in the chart, at $75. Taken together, the data suggest stronger overall spending in Sydney and London than in the other two cities.
Topic sentenceSignals that leisure behaves differently from food and transport
Complex grammar'making it the only city where...' adds an exception through a participle clause
Cohesive device'Taken together' links the final detail back to the full chart
Lexical upgrade'allocated' and 'figure' reduce repetition of 'spent' and 'spending'
ComparisonThe paragraph names the chart's lowest value and reinforces the Sydney/Toronto contrast

Self-Check

Answer these from memory before looking back. If you cannot answer all, re-read the relevant section.

  1. What are the two most important comparison points to identify before writing about a bar chart?
  2. A chart uses dollar amounts. A student writes: 'Food accounted for $170.' What is wrong with this phrase?
  3. Write one sentence comparing London and Sydney using 'whereas' or 'while' and at least one exact figure.
Answers: (1) Identify the highest and lowest values, then decide which bars can be grouped into a clear pattern. (2) 'Accounted for' is percentage/share language; for dollars, write 'households spent $170 on food' or 'food spending stood at $170'. (3) Sample: 'Sydney spent $170 on food, while London spent slightly less, at $160.'
