When presenting data, clear language is as important as the numbers themselves. Avoid just reading out figures — instead, tell the story behind the data. Start with the overall trend: 'Revenue grew steadily throughout the year.' Then highlight the key moments: 'It peaked in Q3, reaching €2.4 million.' Explain any significant changes: 'The decline in Q4 can be attributed to increased competition.' Compare and contrast where relevant: 'Online sales rose by 40%, whereas in-store sales remained flat.' Always end with the implication: 'This suggests we should invest more in our digital channels.' Data without interpretation is just numbers.
