Building Tables Charts and Data Slides

Present numbers accurately with focused tables, appropriate charts and honest visual scales.

What you will learn

• Create readable tables
• Choose a chart that fits the comparison
• Remove visual elements that do not help interpretation

Before you begin

Use a practice presentation and non-sensitive sample information. PowerPoint versions can place commands differently, so use the ribbon search box when a named command is not immediately visible. Save before making major changes.

Design readable tables

Use tables for precise values that the audience needs to compare. Keep headers clear, reduce decimal detail and emphasise only the rows or columns that matter.

Large spreadsheets rarely belong on a slide. Summarise the relevant information or split it into several focused slides.

Choose an honest chart

Column and bar charts compare categories, line charts show change over time and pie charts are suitable only for simple part-to-whole relationships.

Check labels, units and the source. Avoid a misleading axis range, unnecessary three-dimensional effects and decorative elements that distort values.

Explain the conclusion

Give the slide a title that states the main finding. Highlight the relevant series or value and make less important elements quieter.

A chart should support a spoken explanation. If the audience cannot identify the conclusion quickly, simplify the visual.

Guided practice

1. Create a small table with headers and three data rows.
2. Turn suitable practice data into a column or line chart.
3. Add a clear chart title, units and source note.

Knowledge check

1. When should a line chart be used?
2. Why are three-dimensional charts often unhelpful?
3. What should a data-slide title communicate?
