跨文化研究，有時被稱為全文化研究或比較研究，是人類學和姐妹科學（社會學、心理學、經濟學、政治學）的一個專業，它利用來自許多社會的實地數據來檢驗人類行為的范圍，并測試人類行為和文化的假設?？缥幕芯渴强缥幕容^的第三種形式。第一個是案例研究的比較，第二個是共同推導變體之間的控制比較，[需要澄清]，第三個是案例樣本中的比較。與比較研究不同的是，研究少數社會的相似特征，跨文化研究使用足夠大的樣本，以便進行統計分析，以顯示相關特征之間的關系或缺乏關系。這些研究是對人種學數據的調查。跨文化研究廣泛應用于社會科學，尤其是文化人類學和心理學。

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.
