خلفية ثقافية

In German academia and industry, there is a high value placed on 'Nachweisbarkeit' (provability). Using specific statistical terms like ROC analysis demonstrates a commitment to the 'Gründlichkeit' (thoroughness) that German professional culture is famous for. It is a linguistic marker of being a high-level expert.

💡

The AUC Number

In German, we use a comma instead of a decimal point for numbers (e.g., 0,85 instead of 0.85).

⚠️

Gender Matters

Remember that 'Fläche' is feminine (die Fläche). Using 'der' after 'unter' is correct because it's in the dative case here.

What It Means

Imagine you built a smart tool to predict the weather. You need to know if it is actually good or just guessing. The ROC-Kurvenanalyse is the mathematical test you run to find out. When you say Die ROC-Kurvenanalyse ergab eine Fläche unter der..., you are about to give the final score. Usually, you finish the sentence with Kurve von 0,85 or a similar number. It is the gold standard for measuring how well a binary classifier works. In simple terms, it tells you the probability that your model gets it right.

How To Use It

You will mostly use this in written reports or formal presentations. It is a very specific, technical phrase. You start with the subject Die ROC-Kurvenanalyse. Then use the verb ergab to show the result. Finally, you mention the Fläche unter der Kurve (Area Under the Curve). You can follow it with a specific value. It sounds very professional and precise. It shows you know your statistics. Even in a casual office setting, keep the structure formal. Data nerds love this kind of precision over coffee.

When To Use It

Use this when you are presenting your thesis results. It is perfect for medical studies or machine learning projects. Use it in a meeting with your lead developer. It fits well in a peer-reviewed journal article. If you are explaining why a new diagnostic test is reliable, this is your go-to phrase. It signals that your findings are backed by rigorous math. It is the language of evidence-based truth.

When NOT To Use It

Do not use this at a birthday party. Your friends will think you forgot how to be human. Avoid it when talking to people who do not work with data. It is too jargon-heavy for a general audience. Do not use it if you only have a small sample size. It might make you look like you are over-complicating things. If the result is obvious, just say it is good. No need for the full statistical mouthful.

Cultural Background

Germany has a deep-rooted culture of engineering and scientific excellence. Precision is not just a stereotype; it is a linguistic requirement in research. German academic language is very structured and formal. This phrase reflects that love for exactness. In German universities, being vague is a cardinal sin. Using the full name of the analysis shows respect for the methodology. It is part of the 'Fachsprache' (technical language) that defines professional identity.

Common Variations

You might hear people say Der AUC-Wert liegt bei... for short. Some might say Die Fläche unter der ROC-Kurve beträgt.... In a more active voice, you could say Wir berechneten die Fläche unter der Kurve. However, starting with the analysis as the subject is very common. It makes the data the 'hero' of the sentence. You can also add adjectives like signifikante before Fläche. This adds even more weight to your statement.

ملاحظات الاستخدام

This is a high-level C1 academic phrase. It requires correct usage of the dative case after 'unter' and the specific verb 'ergeben'. It is almost exclusively used in written or spoken technical reports.

The 'Ergab' Secret

Germans love the verb 'ergeben' for results because it sounds objective. It implies the data spoke for itself.

It stands for 'Receiver Operating Characteristic'. Even in German, we use the English acronym, though we add the German word Kurvenanalyse to it.

No, it is strictly for professional or academic contexts. Using it while grocery shopping would be very confusing!

You could, but ergab is much more common and natural in scientific German. Resultierte in sounds like a direct translation from English.

It is the 'Area Under the Curve' (AUC). It represents the probability that the model ranks a random positive example higher than a random negative one.

In casual professional talk, you can just say Die ROC-Analyse, but ROC-Kurvenanalyse is the precise full term.

No, it is also very common in medicine to test how well a diagnostic test identifies a disease. It is a cross-disciplinary term.

It is formal. It belongs in the Fachsprache (technical jargon) category used by experts.

You would say: Die Analyse ergab eine geringe Fläche unter der Kurve. A value near 0,5 is considered poor.

Because unter is a preposition that takes the dative case when describing a location (where the area is). Die Fläche becomes der Fläche.

Only if you are texting a fellow student or colleague about work results. Otherwise, it is too stiff.

Yes, you can simply say Der AUC-Wert ist.... It is much faster and very common in tech offices.
