| Read time | What to take away |
| 1 second | Organise the data first; the calculation is easier after the table is clean. |
| 10 seconds | Use mean, median, mode, range, IQR, and standard deviation to describe different parts of a dataset. For scatter plots, say correlation, not cause. |
| 100 seconds | Work through the grouped-table examples to practise cumulative frequency, percentiles, and clear interpretation sentences that compare centre, spread, and pattern. |
Statistics questions reward tidy tables and well-labelled graphs. Document your calculator steps so you can replicate them under exam conditions.
