My native language is English and I'm fluent and well educated.
Although I do know that "average" covers mean, median and mode, when I was young I was not taught that way. First I was just taught "average" with a formula, and many years later "median" and "mode". I don't think I noticed the term "mean" until I learned about median and mode.
You can see this reflected in scientific calculators used at school, where the button for calculating mean is labelled "Avg".
And in Microsoft Excel or LibreOffice Calc, the function to calculate mean is called "AVERAGE".
So nobody should be hard on themselves for not knowing the difference. You probably weren't taught the difference, and common tools work against it.
It looks to me that the common word for statistical mean is "average" in English, but it's not the correct technical language.

Absolutely, which is why I think being hard on someone for not knowing the difference between "the average" and the median is similarly an issue.
- pmiller2 6y agoYou realize that an interview is not the same as writing a technical article, right? It should be a conversation between two potential coworkers, and, in that context, I think saying "average" instead of "mean" is totally fine. Incidentally, "mean" doesn't quite cut it, if you want to be a stickler about it. There are several types of means: arithmetic, geometric, harmonic, etc. By that standard, you just failed the interview.
