Contexte culturel
This phrase reflects the German emphasis on 'Genauigkeit' (accuracy) and 'Transparenz' (transparency) in scientific work. As Germany positions itself as a leader in AI and automation, technical vocabulary like this has moved from niche labs into mainstream corporate German.
The 'Zu' Rule
When speaking, the colon (:) is pronounced as 'zu'. So '80:20' is 'achtzig zu zwanzig'.
Don't forget the verb!
Since this phrase usually starts with 'wurden' (passive voice), the main verb like 'aufgeteilt' must go at the very end of the sentence.

What It Means
Imagine you are teaching a dog new tricks. You use some treats to train him and save some to see if he remembers later. In the world of data science, this phrase is the formal way to say how much data you used for the teaching part versus the testing part. It is the backbone of any machine learning project. You are essentially setting the stage for your experiment's validity. It tells your audience exactly how you partitioned your resources.
How To Use It
You will almost always see this followed by two numbers. For example, 80 zu 20 or 70:30. You need a verb at the end to finish the thought. Usually, that verb is aufgeteilt (split) or verteilt (distributed). You say: Die Trainings- und Testdaten wurden im Verhältnis 80 zu 20 aufgeteilt. It sounds very professional and precise. It shows you know your statistics. You can also use it in written reports. Just make sure the numbers add up to 100 or a logical ratio!
When To Use It
Use this when you are presenting your results. If you are in a meeting with developers, this is your go-to phrase. It is perfect for your Master's thesis in computer science. Even in a casual chat with a fellow nerd, it works. It signals that your methodology is sound. It is a staple of the 'Data Science' German dialect. You will hear it in tech hubs like Berlin or Munich constantly.
When NOT To Use It
Do not use this at a party when talking about drinks. If you say your Gin and Tonic is im Verhältnis 1 zu 3, people might think you are still at the office. It is too clinical for romance. Don't tell your partner your love is split in a 50:50 ratio. That sounds like a legal contract, not a relationship. Stick to simpler words like halb-halb for everyday life. It is strictly for data and technical contexts.
Cultural Background
Germany is famous for engineering and precision. This carries over into the digital age. 'Industrie 4.0' is a huge buzzword here. Germans value transparency in how results are achieved. By stating the ratio clearly, you are following a tradition of technical clarity. It is about Ordnung (order) even in your code. The tech scene is international, but this German phrasing remains standard in formal documentation.
Common Variations
You might hear Das Split-Verhältnis beträgt.... Or more simply, Wir haben 80/20 gesplittet. Some people use the English word Split even in German. Another version is Die Aufteilung der Daten erfolgte im Verhältnis.... All of these mean the same thing. They just vary in how much 'Denglish' (German-English mix) you want to use. The version with Verhältnis is the most elegant and 'correct' for high-level German.
Notes d'usage
This is a high-level technical expression. Use it in professional or academic settings to sound authoritative. Avoid it in casual, non-tech social situations.
The 'Zu' Rule
When speaking, the colon (:) is pronounced as 'zu'. So '80:20' is 'achtzig zu zwanzig'.
Don't forget the verb!
Since this phrase usually starts with 'wurden' (passive voice), the main verb like 'aufgeteilt' must go at the very end of the sentence.
Denglish is okay
In modern German IT offices, saying 'gesplittet' is often more common than 'aufgeteilt', but 'im Verhältnis' stays the same.
