The data-selection trap is treating Task 1 like a transcription exercise, every bar, every year, every percentage. Examiners reward a clear overview plus selective, compared detail. Kitchen-sink reports bury the main trend, waste word count, and often skip the highest/lowest contrast examiners expect at Band 7+.

How the trap shows up
Selection traps that cap Task Achievement
| Trap | Why it fails |
|---|---|
| Irrelevant detail | Minor years over main gap |
| No comparison | Numbers without contrast |
| Word-count panic | Listing to hit 150 words |
| Accuracy praised | All figures named, overview weak |
Contrast with data grouping error.
Fix: overview first, then select
Write the overview from two or three key features only. Each body paragraph supports one feature with paired figures, not new unrelated stats.
Key takeaways: Data Selection Traps in IELTS Task 1
- Task 1 is summary and selection, not full description.
- Overview drives which data you include.
- Extremes and clear comparisons matter more than volume.
- Omitting minor fluctuations is expected, not risky.
