Contexte culturel
The term 'Stichprobe' comes from the historical practice of 'stechen' (pricking) a sack of grain to take a small sample without opening the whole bag. This reflects the German emphasis on 'Gründlichkeit' (thoroughness) and 'Präzision' (precision) in scientific and bureaucratic processes. It became a staple of academic German during the rise of social sciences in the 20th century.
The 'Sich' Secret
Don't forget the 'sich'! It's a reflexive verb. If you leave it out, the sentence breaks. Think of it as the amount 'running itself' up to a certain point.
Don't Over-Science It
Using this for everyday items (like apples in a basket) will make you sound like a robot. Use 'beträgt' or 'ist' for simple counts.

What It Means
Imagine you are conducting a big survey. You cannot ask every single person in the country. You pick a small group instead. This group is your Stichprobe. The phrase tells everyone the exact number you need. It sounds very official and scientific. It means 'The total number we need is...' and implies you have done the math.
How To Use It
Start with the subject Die erforderliche Stichprobengröße. Then add the reflexive verb beläuft sich. Always include the preposition auf. Finally, state your number. It works like a mathematical formula. Use it when presenting data or plans. It shows you have calculated your needs carefully. You are being precise and professional.
When To Use It
Use this in university seminars or thesis papers. It is perfect for professional business reports. Use it when talking to data scientists. It fits well in medical research contexts. Use it whenever precision is your top priority. It makes you sound like a serious expert. Even a marketing meeting can benefit from this level of detail.
When NOT To Use It
Do not use this at the dinner table. 'The required sample size of peas is twenty' sounds very weird. Avoid it in casual chats with friends. It is too heavy for a quick text. Do not use it for simple counting. Use Es sind for basic numbers instead. Keep it for serious analytical moments only.
