What Should You Focus On?

- periods of stability
- fluctuations
- similarities and differences between trends
Strategy for Writing - Trend Data
STEP 1. Understand the Task
The instructions are always the same: "Summarise the information by selecting and reporting the main features, and make comparisons where relevant."
For trend data, "main features" usually means the biggest changes over time.
STEP 2. Plan Your Answer (4-Paragraph Structure, at Least 150 Words)
1. Paraphrase the description
2. Write an overview paragraph
3. Write two body paragraphs
STEP 3. Choose the Right Grouping Method
For trend data, you can group information by:
- lines/categories that increased
- lines/categories that decreased
- lines/categories with similar patterns
- lines/categories with opposite patterns
- earlier period vs later period
- most dramatic changes vs more stable changes
※ No conclusion needed.
Line Graph
What Line Charts Usually Show
Line charts show changes over time.
They may show changes in:
- population, sales, income, spending, unemployment rates, energy use, student numbers, internet usage, birth rates, production levels, etc.
Your job is to describe the main trends, not every point on the line.
Two Main Types of Line Charts
Single-line charts
These show the change of one category over time.
For single-line charts, focus on:
- where the figure started
- whether it rose, fell, fluctuated, or stayed stable
- the highest and lowest points
- where the figure ended
Useful language
- increased steadily
- declined gradually
- fluctuated noticeably
- remained stable
- reached a peak
- fell to its lowest point
- ended higher/lower than it began
Multiple-line charts
These show changes in two or more categories over time.
For multiple-line charts, focus on:
- which line was highest or lowest at the start
- which line was highest or lowest at the end
- which line increased or decreased the most
- whether any lines crossed
- whether the categories followed similar or opposite trends
Useful language
- X rose more sharply than Y
- X remained higher than Y throughout the period
- X overtook Y in 2010
- X and Y followed similar upward trends
- X increased, while Y declined
Essay Structure for Line Charts (4 Paragraphs)
1) Introduction
- Paraphrase the description of the chart
2) Overview Paragraph
- Summarize 2–3 of the most prominent trends
- Mention the general direction of change
- Do not include specific figures
3) Body Paragraph 1
- Describe the first main group of data. Possible grouping methods:
- categories that increased
- the highest or most important line
- the first half of the time period
- lines with similar trends
4) Body Paragraph 2
- Describe the remaining major data. Possible grouping methods:
- categories that decreased
- lower or less important lines
- the second half of the time period
- lines with contrasting trends
※ No conclusion needed.
Reminders
1. Spend only 20 minutes on Task 1
Task 1 is worth half of the Task 2 score.
2. Do not describe every data point
Focus on the beginning, end, peak, low point, and major changes.
3. Focus on the overall trend first
Before writing details, decide whether each line generally rises, falls, fluctuates, or stays stable.
4. Compare the lines, not just the numbers
In multiple-line charts, explain how the trends are similar or different.
5. Be careful with units
Always check whether the chart shows percentages, numbers of people, millions, dollars, hours, or another unit.
