跨文化研究，有時(shí)被稱為全文化研究或比較研究，是人類學(xué)和姐妹科學(xué)（社會(huì)學(xué)、心理學(xué)、經(jīng)濟(jì)學(xué)、政治學(xué)）的一個(gè)專業(yè)，它利用來(lái)自許多社會(huì)的實(shí)地?cái)?shù)據(jù)來(lái)檢驗(yàn)人類行為的范圍，并測(cè)試人類行為和文化的假設(shè)。跨文化研究是跨文化比較的第三種形式。第一個(gè)是案例研究的比較，第二個(gè)是共同推導(dǎo)變體之間的控制比較，[需要澄清]，第三個(gè)是案例樣本中的比較。與比較研究不同的是，研究少數(shù)社會(huì)的相似特征，跨文化研究使用足夠大的樣本，以便進(jìn)行統(tǒng)計(jì)分析，以顯示相關(guān)特征之間的關(guān)系或缺乏關(guān)系。這些研究是對(duì)人種學(xué)數(shù)據(jù)的調(diào)查。跨文化研究廣泛應(yīng)用于社會(huì)科學(xué)，尤其是文化人類學(xué)和心理學(xué)。

Cross-cultural studies, sometimes called holocultural studies or comparative studies, is a specialization in anthropology and sister sciences (sociology, psychology, economics, political science) that uses field data from many societies to examine the scope of human behavior and test hypotheses about human behavior and culture. Cross-cultural studies is the third form of cross-cultural comparisons. The first is comparison of case studies, the second is controlled comparison among variants of a common derivation,[clarification needed] and the third is comparison within a sample of cases. Unlike comparative studies, which examines similar characteristics of a few societies, cross-cultural studies uses a sufficiently large sample so that statistical analysis can be made to show relationships or lack of relationships between the traits in question. These studies are surveys of ethnographic data.Cross-cultural studies are applied widely in the social sciences, particularly in cultural anthropology and psychology.
