Apologies accepted for being pedantic and not knowing that a proper study would include statistical averages as part of the results but also conclusions in form of statements that I purposely called "generalizations". But of course I do not expect any references to the nonexistent study.
Averages in the number of instances of a particular behavior can be calculated.
Yes, but the numbers themselves can't tell any story to the people not familiar with statistics or the field of study. That's why we have results interpretation to find the insights that would explain said behaviour.
(For e.g. of the result of a study could be: in one country the phrase "You're welcome" is used on average 22 times per day as observed on a the group that is being studied, whereas "De nada" was used 8 times per day on average as observed on another group of a similar age and social status in another country).
And when those averages are different from one country to another that is interesting to know, and it can, sometimes, explain misunderstandings between 2 nationals of different countries.
I forgive you for completely missing the point about my expression "National Study that allows you to make generalizations about an entire country" because that would be complete non-sense. Brazil is a nation of 213 Million, just as big as the US, with massive economic and social inequalities across the entire population. Even if possible to be calculated, anyone saying that national averages could be used to describe every single element of a diverse universe of 213 million is just delusional.

You can do cultural studies by just stating facts and reporting what you find. You don't have to make "generalizations".
Yes, generalizations don't apply. And no, you can't do a cultural study by just reporting and stating facts. It's not Accounting, it's Human / Social Sciences (reference in my comment above).
TO CLOSE: Insinuating ( as some have, at the beginning of this thread ) that all Brazilians have an ungrateful culture is misguided and falls into xenophobia and racism, so please stop it.
