Die Paralleltest-Reliabilität wurde ermittelt durch

You’ll mostly find this phrase in the 'Methodology' or 'Results' section of a scientific paper. It follows a very specific grammatical recipe: the subject (Die Paralleltest-Reliabilität), a passive verb construction (wurde ermittelt), and a prepositional phrase (durch + whatever method you used). Because it’s so formal, you should avoid using it when chatting with friends or ordering a Döner. Unless, of course, you want your friends to think you’ve finally lost it after studying for your finals. To use it correctly, you need to follow durch with a noun in the Dative case. For example, durch den Vergleich (through the comparison). Just remember, German loves nouns. The longer the noun, the more 'scientific' you sound. It’s like building a Lego tower out of words.

This phrase lives at the very top of the formality mountain. It is 'Very Formal.' You won’t see it on TikTok (unless it's a very niche statistics meme) or in a casual WhatsApp group. It belongs in academic journals, university theses, and formal psychological reports. Using this in a casual setting is like wearing a tuxedo to a beach party—impressive, but very out of place. The register is strictly objective. We use the passive voice (wurde ermittelt) because in German science, the 'who' doesn't matter as much as the 'what.' It’s not about *you* finding the results; it’s about the results being *found* by the process. It’s very humble in a weirdly arrogant way.

Picture a student named Lukas. Lukas is writing his Master’s thesis in Psychology. He writes: Die Paralleltest-Reliabilität wurde ermittelt durch die Korrelation der beiden Testformen. This sounds professional and gets him an A. Now imagine a pharmaceutical company testing a new drug’s side effects survey. They might report: Die Paralleltest-Reliabilität wurde ermittelt durch die zeitnahe Durchführung von Form A und B. Even in educational settings, like when the government tests high school students, they use this phrasing to prove the exams are fair. You might also see it in software documentation for high-end data analysis tools like SPSS or R. It’s the language of people who love spreadsheets more than sunlight.

Use this phrase when you are writing anything that will be graded by a professor or reviewed by a scientist. It’s perfect for the 'Methoden' (Methods) section of a report. If you are presenting a poster at a conference, this is your go-to line to explain your data’s quality. You can also use it in formal business contexts if you’re dealing with HR analytics or quality control. Basically, if there’s a graph involved and you need to prove the graph isn't lying, this is your phrase. It’s a great way to show off your C1-level German skills because it shows you understand complex syntax and academic conventions. Plus, it’s a great way to fill up word counts in a thesis!

Do not use this while on a first date. 'Hey, the parallel-test reliability of our chemistry was determined through my heart rate' is a one-way ticket to a lonely evening. Avoid it in emails to colleagues unless you work in a lab. Never use it in a text message, even if you’re talking about a test. If you say this to a waiter when they ask how your food is, they will probably just walk away slowly. It’s too heavy for daily life. It’s like trying to use a scalpel to cut a birthday cake—technically possible, but totally the wrong tool for the job. Keep it in the ivory tower where it belongs.

One major trap is using the wrong preposition. ✗ Die Paralleltest-Reliabilität wurde ermittelt *mit*... → ✓ Die Paralleltest-Reliabilität wurde ermittelt *durch*.... While mit (with) makes sense in English, durch (through/by) is the standard academic choice here. Another mistake is using the active voice. ✗ Ich ermittelte die Paralleltest-Reliabilität durch.... In German academia, saying 'I' (Ich) is often seen as too informal or subjective. Stick to the passive wurde ermittelt. Also, watch out for the case after durch. It must be Accusative, but since we often use abstract nouns, it can get tricky. ✗ durch der Vergleich → ✓ durch den Vergleich. If you mess up the case, the statistics might be right, but the grammar will make a professor’s eye twitch.

If you want to spice things up (as much as statistics allows), you can swap the verb. Instead of ermittelt, you could use bestimmt (determined) or berechnet (calculated). So, Die Paralleltest-Reliabilität wurde bestimmt durch.... You might also see mittels instead of durch. Mittels is even more formal and means 'by means of.' For example: Die Paralleltest-Reliabilität wurde mittels Pearson-Korrelation berechnet. Another variation is the 'Substantivierung' (noun-heavy style): Die Ermittlung der Paralleltest-Reliabilität erfolgte durch.... This is the final boss level of German academic writing. It’s essentially a sentence made of nouns that have forgotten they were once verbs.

Is this phrase common? In daily life, absolutely not. In a university library? You’ll hear it every five minutes. Can I use it in an email? Only if the email is to a research supervisor or a scientific journal editor. Does 'Reliabilität' mean 'Reliability'? Yes, but specifically in a technical, statistical sense, not 'my friend is reliable.' Why is it so long? Because German loves to smash words together like Parallel, Test, and Reliabilität. It’s efficient, but a mouthful. Do I really need the passive voice? Yes, it’s the standard for German 'Wissenschaftssprache' (scientific language). It makes the research sound like it happened on its own, untainted by human error.
