Improve the design without changing the message
Keep a readable chart and a short, evidence-based explanation.

Keep using your working copy if you have started the programme.
Practice workbook (.xlsx)Learn the skill
Design should make the evidence easier to read, not exaggerate differences or hide uncertainty.
Worked example
Use a calm, high-contrast style, readable text and a simple 2-D layout.
North has the highest cost at £250; total cost is £540. This does not prove North is inefficient.
Avoid 3-D effects, decorative backgrounds and colour-only meaning.
Follow these steps
- Save your finished practice copy.
- Try one chart style and inspect text contrast and labels.
- Check the source range and values again after the style change.
- Review at a normal screen size and in File > Print preview. Do not print unless you need to.
- Write one supported observation and one limit of the data.
Try it yourself
Keep your chart and a two-sentence handover: what the data shows, and what it cannot establish. Reconcile the chart back to the eight source orders.
Check your practical result
- The chart remains 250, 200, 90 with total £540.
- The design is readable without relying on colour.
- Your interpretation does not turn cost differences into unproven performance claims.
This is your own review, not an automatic inspection of Excel.
If it does not work
If a style hides labels or adds clutter, revert to a simple 2-D style. If the numbers changed, stop and inspect the source before formatting further.
