- Construct and interpret tables and different types of charts
- Recommend appropriate formats for presenting given types of information
- Interpret management information in visual form for decision making
Test Your Knowledge
Attempt these questions before reading this article. If you find some difficult or cannot remember the answers, remember to look more closely at that area during your revision.
- Which type of chart is most appropriate to show how monthly sales figures have changed over a year?

- True or false? Pie charts are suitable for displaying trends over time.
- List two key elements that a well-constructed table should include.
Introduction
Presenting management information in clear, concise, and easily interpreted formats is essential for effective decision making. Tables, charts, and graphs help convert raw data into information that can be quickly understood by managers. Choosing the right format for data presentation is critical to avoid misinterpretation and ensure reports are actionable.
Effective presentation aids users in recognising patterns, making comparisons, and identifying key trends. For ACCA Management Accounting (MA) exam, you must demonstrate the ability to present data using tables, bar charts, line graphs, pie charts, and scatter diagrams, as well as interpret the information shown.
PRESENTING DATA: TABLES AND VISUAL FORMATS
Tables
Tables summarise and organise data in rows and columns, allowing detailed comparison and easy reference.
Key Term: Table
A structured arrangement of data in rows and columns that systematically presents quantitative or qualitative information for analysis.
A good table contains a clear title, labelled columns and rows, specified units of measurement, and, where necessary, the data source. Headings should be concise, enabling quick understanding. Totals and subtotals should be included if meaningful.
Bar Charts
Bar charts (also called bar graphs) use rectangular bars to represent values for different categories. Bar charts make it easy to compare discrete items, like product sales by region.
Key Term: Bar Chart
A graph that represents categorical data with rectangular bars whose height or length is proportional to the value represented.
The x-axis usually shows the category labels, while the y-axis shows the measurement scale. Bars are separated by spaces to emphasise the categories are distinct. Compound and component bar charts allow for further breakdown of data within each category.
Line Graphs
Line graphs represent the trend of continuous data, most often over time, using data points connected with lines.
Key Term: Line Graph
A chart displaying values of a variable at different points, typically used to illustrate trends or changes over time.
Time series data—such as monthly profits or costs—are ideal for line graphs. Multiple series can be plotted on the same graph for direct comparison.
Pie Charts
Pie charts show how a whole quantity is divided into proportional parts.
Key Term: Pie Chart
A circular chart divided into sectors, with each sector representing a proportion of the total.
Pie charts are best for displaying a single data series, not trends. Each ‘slice’ of the pie represents the percentage contribution of that category to the overall total.
Scatter Diagrams
A scatter diagram (scatter graph) is used to show relationships or correlations between two numerical variables.
Key Term: Scatter Diagram
A graph plotting two quantitative variables as points, used to investigate correlation or patterns between them.
Each axis represents one variable and each point shows their paired value. Patterns in the point distribution can reveal associations, trends, or outliers.
CHOOSING THE CORRECT FORMAT
Selecting the right way to present data is essential:
- Tables: best for detailed values allowing precise comparison.
- Bar charts: for comparing discrete categories or groups.
- Line graphs: for showing trends or progressions over time.
- Pie charts: for displaying proportions within a whole.
- Scatter diagrams: for analysing relationships between two quantitative variables.
Worked Example 1.1
Question:
You are asked to report monthly unit sales for four products in three regions over a year.
Which format(s) are most suitable to: (a) Allow the regional manager to see the exact sales by product and region for any given month? (b) Enable the sales director to quickly compare the share of each region in total annual sales?
Answer:
(a) A table with months as rows, products/regions as columns, including subtotals. (b) A pie chart showing each region’s percentage of the total annual sales.
PRACTICAL CONSTRUCTION AND BEST PRACTICES
- Clearly label all axes, columns, and rows.
- State units (e.g. £000s, units, %).
- Use a descriptive title for all visuals.
- For bar/line charts, use a suitable scale and ensure gridlines or bars do not mislead.
- In pie charts, limit number of categories to six or fewer for clarity.
- Avoid 3D effects or unnecessary decorations that hinder correct reading.
- When appropriate, use data labels to avoid misinterpretation.
Worked Example 1.2
Question:
A survey collects customer satisfaction ratings (on a 1–5 scale) for three service branches. What chart type is best to compare customer satisfaction distributions between branches?
Answer:
A grouped (compound) bar chart allows comparison of satisfaction rating frequencies across branches. Alternatively, a percentage component bar chart shows the relative distribution within each branch.
INTERPRETING VISUAL INFORMATION
Being able to interpret management information presented in tables or graphs is as important as creating them. Look for:
- Main trends and changes
- Exceptional values or outliers
- Largest/smallest groups
- Proportions and comparisons
If commenting on visuals in a report or during the exam, provide concise summaries (e.g., "Sales rose steadily from April to July, peaking in June before declining").
Key Term: Data Visualisation
The graphical representation of numerical or qualitative information designed to communicate patterns, trends, or comparisons effectively.
Revision Tip
When reviewing a chart or table in the exam, take 10 seconds to identify the title, axes, units, and main message before interpreting further.
COMMON ERRORS AND EXAM WARNINGS
Exam Warning
Pie charts are often misused to show trends or comparisons across multiple years. Avoid this—use line graphs for trends and bar charts for multi-period categorical comparisons.
Errors to avoid:
- Using too many categories in a pie chart.
- Failing to label axes or sectors clearly.
- Choosing inappropriate scales in bar/line graphs.
- Using non-zero baselines for bar or line charts, which can distort comparisons.
Worked Example 1.3
Question:
You are asked to show the relationship between advertising spend and sales revenue for a set of campaigns. How would you present this, and how would you check if there is a relationship?
Answer:
Use a scatter diagram: plot advertising spend on one axis and sales revenue on the other, with each campaign as a point. If the points form an upward trend, a positive correlation exists.
Summary
Management information must be presented in the most effective manner for its purpose. Tables provide detailed, precise information for reference. Charts and graphs—bar, line, pie, and scatter—help reveal trends, relationships, and patterns at a glance. Using correct formats, clear labelling, and good design supports meaningful decision-making and prevents misunderstanding.
