TestDaF TDN 4 Speaking Task 6 – Describing a graphic and forming hypotheses
Task 6 of the Oral Expression is about: describing a graphic and forming hypotheses. Here’s how to respond to the situation correctly.
As of 2026 · Built to the official exam format
Key takeaways
- You describe a graphic and form conjectures about the causes.
- Describe the essentials and justify your hypotheses.
What this part tests
Task 6 tests whether you can describe a graphic and, beyond that, form hypotheses about causes or backgrounds – a more demanding speech act.
You first give the most important data of the graphic and then form justified conjectures about why the development happens.
What matters is a clear graphic description and plausible, linguistically marked hypotheses (“könnte daran liegen, dass …”, “ein möglicher Grund ist …”).
How to approach it
- 1
Introduce the graphic and describe the most important development.
- 2
Mark the transition to your conjectures.
- 3
Form one or two hypotheses about the causes.
- 4
Justify your hypotheses plausibly.
- 5
Sum up briefly at the end.
Example task with answer
A short example in the same format: the situation and a model answer.
Eine Grafik zeigt: Die Zahl der Menschen, die online einkaufen, ist stark gestiegen. Beschreiben Sie die Grafik und stellen Sie Vermutungen über die Gründe an.
Model answer:
Why? The answer first describes the graphic’s development and then forms justified hypotheses about the causes, clearly marked as conjectures – exactly what Task 6 expects.
Practice: test yourself
Eine Grafik zeigt: Die Zahl der Fahrradfahrer in der Stadt ist stark gestiegen. Du sollst die Grafik beschreiben und Vermutungen über die Gründe äußern.
Which sentence forms a justified hypothesis?
Common mistakes
Task 6 also requires hypotheses. Don’t stop at the description.
Use phrases like “könnte daran liegen, dass …” to mark conjectures clearly.
Your hypotheses should fit the topic and be justified.
Justify why you suspect a particular cause.
Tips
- Separate clearly: first describe, then hypotheses.
- Use hypothesis phrases (“ein möglicher Grund könnte sein, dass …”).
- Justify each conjecture briefly.
