These files include raw data collected for my thesis "Home and Preschool Influences on Early Child Development of Ethnic Majority and Minority Children". There are three files. They are the datasets for Study 3 (Home and Preschool Influences on Early Child Development of Chinese and South Asian Children), 4 (A Home-based Intervention to Promote Intrinsic Reading Motivation and Oral Vocabulary of South Asian Children in Hong Kong), and 5 (A Classroom-based Intervention to reduce Chinese Children's Anti-South Asian bias) separately.
