Contexto cultural
This phrase is a hallmark of the 'Evidence-Based' movement in global academia and industry. It reflects a cultural shift toward transparency where 'showing your work' is just as important as the result itself. It is universally recognized in international research as a standard way to report statistical rigor.
The Passive Voice Power
Using 'was calculated' instead of 'I calculated' makes your writing sound more objective and scientific.
Don't Overuse It
Only use this for actual statistical variance. If you just mean 'difference,' use a simpler word like 'difference' or 'change.'

What It Means
When you are doing research, you often need to show how 'spread out' your numbers are. This spread is called variance. By saying variance was calculated as, you are telling your reader exactly which steps you took to get that number. It is like showing your work on a math test so the teacher knows you didn't just guess. It turns a vague number into a credible fact.
How To Use It
You will almost always find this phrase in the 'Methodology' or 'Results' section of a paper. It is usually followed by a formula, a specific software name, or a description of a statistical test. For example, you might say, variance was calculated as the square of the standard deviation. It sounds very professional because it uses the passive voice, which focuses on the action rather than the person doing it.
When To Use It
Use this when you are writing a formal report, a thesis, or a business analysis. If you are presenting data to a boss who loves details, this phrase is your best friend. It shows you are precise and transparent. It is perfect for science labs, financial audits, or even a deep dive into your personal fitness tracking data if you are feeling extra nerdy.
When NOT To Use It
Do not use this at a party or while grabbing coffee with a friend. If you say, 'The variance in my latte temperature was calculated as...', people will think you are a robot. Avoid it in casual emails or text messages unless you are joking. It is too heavy and technical for everyday conversation. Keep it in the office or the classroom.
Cultural Background
In Western academic and business culture, there is a huge emphasis on 'data-driven' decisions. This phrase became a staple during the 20th century as statistics became the backbone of modern science. Being able to explain your math clearly is a sign of high-level education and professional integrity. It tells the world that you value logic over feelings.
Common Variations
You might also see variance was determined by or variance was computed using. If you want to sound slightly less formal but still professional, you could say we calculated the variance by. However, in most serious journals, the original phrase remains the gold standard. It’s the 'suit and tie' of the statistics world.
Notas de uso
This phrase is strictly for formal, technical, or academic writing. It uses the passive voice to maintain an objective tone, which is the standard in scientific reporting.

The 'Smart' Signal
In English-speaking corporate environments, using statistical terms correctly is a 'shibboleth'—a way to signal you are highly trained.
