This term is widely used in academic, scientific, and statistical contexts in both Brazil and the United States. In Brazilian Portuguese, while 'selecionado aleatoriamente' is the standard translation, younger professionals and tech workers sometimes use the English loanword 'randomicamente' in technical discussions. The concept is fundamental to research methodology and data collection practices across both cultures.
