What a pie chart is actually asking
A pie chart shows one whole divided into parts. That is all it does, and the whole of what Task 1 asks for follows from that.
Your job is to report the proportions accurately, compare the slices, and say which matter most. It is a description, not an argument. "This suggests the government should redirect spending" is the sentence that fails a Task 1, however well written it is.
Two numbers on a pie chart always add to 100, so the chart is telling you the answer to the arithmetic. Your job is not to add them up. It is to decide what is worth a sentence and what is not.
Group before you write
This is where a pie chart answer is won, and it happens in the first thirty seconds before you write anything.
Look at the slices and find the shape the data has. Almost always one of four:
- One dominant slice and several small ones. Describe the dominant slice, then group the rest.
- Two or three comparable slices that together dominate. Describe those together, then the tail.
- A clear leader and runner-up. Describe both, then the remainder as a group.
- A fairly even spread, where no slice dominates. Say so in the overview and group by size: "the three largest categories accounted for almost three-quarters of the total".
Decide the grouping first. The overview sentence and the paragraph order both follow from it. A candidate who starts writing sentences before finding the grouping produces accurate text with no shape, and "does not have a clear overview" is a criterion you can be failed on.
The overview paragraph
Most candidates skip this. It is one or two sentences describing the most striking feature of the whole chart, with no numbers in it.
Using a household spending chart:
- Good: "Housing took by far the largest share of household spending, while recreation and clothing accounted for the smallest proportions."
- Not an overview: "Housing accounted for 35 percent, food for 25 percent and transport for 15 percent."
The second is a data sentence. It does the job the body should be doing, and the overview slot stays empty.
The body: compare, do not list
Listing is the common failure. "X was 30 percent. Y was 25 percent. Z was 18 percent." is accurate and earns very little.
Compare instead:
- Across slices: "Housing spent almost twice as much as food, at 35 percent compared with 20."
- As a share of one slice: "Transport accounted for under half of what housing cost."
- Combined: "Food and transport together made up a little over a third of total spending."
- Proportional: "Clothing took roughly one-sixth as much as housing."
A good body alternates between description and comparison, roughly two sentences of description for each sentence of comparison.
Language for proportions
Naming shares: the largest proportion, the dominant share, the biggest category, the least significant category, the smallest proportion, a negligible share.
Approximating: approximately, just under, just over, roughly, a little over, about, close to, marginally.
Proportional phrases: twice as much as, half as much as, more than double, roughly a third of, three times as much, a fraction of.
Grouping the tail: "All other categories together accounted for the remaining 12 percent", "The remaining items made up less than a tenth of the total".
What to leave out
- The chart title. Rewriting the question is the introduction's job, not a separate observation.
- Every slice individually. Six slices described one per sentence is a list, not a description, and it says nothing.
- The axis. A pie chart has no axis.
- Precision the chart does not have. "34.7 percent" reads as false precision on a chart labelled in whole numbers. "About 35 percent" is both more accurate and better English.
- Any opinion.
Five mistakes that cost marks
- No overview. Required, frequently missing, and cheap to fix.
- Listing instead of comparing. Accurate and nearly worthless.
- Describing every slice. You run out of words and still have not grouped.
- Rounding in the wrong direction. If a slice is 49.5, "just under half" is right. If it is 50.5, "just over half".
- Opinion creeping in. Any "this shows that", "this means" or "therefore" is out of scope.
A structure that holds up
- Introduction, one sentence paraphrasing the question
- Overview, one or two sentences, no numbers
- Body paragraph one, the dominant slice or the leading group
- Body paragraph two, everything else, closed with a comparison
Target 140 to 190 words. Check the count before you stop; under 140 loses marks outright, and when you are short the overview is the first thing to cut, which is the wrong thing to cut.
How to practise
Write the overview first and only that, one sentence, no numbers. Time it at one minute. Do this for a dozen pie charts and the overview stops being the part you forget, which is the entire point.
Self-marking does not work well on Task 1. The errors are the ones you cannot see while you are making them, so get one properly marked against the published descriptors rather than writing five and checking none.
