Package: WSCdata Title: A New Four-Arm Within-Study Comparison Data on Math and Vocabulary Training Version: 0.1.1.9000 Authors@R: c(person("Bryan","Keller", ,"keller4@tc.columbia.edu", role=c("aut", "cph")), person("Sangbaek","Park", , "qkr800507@gmail.com", role=c("aut", "ctb")), person("Jingru","Zhang", , "jzhang2637@wisc.edu", role= c("aut", "cre"))) Description: This dataset was collected using a new four-arm within-study comparison design. The study aimed to examine the impact of a mathematics training intervention and a vocabulary study session on post-test scores in mathematics and vocabulary, respectively. The innovative four-arm within-study comparison design facilitates both experimental and quasi-experimental identification of average causal effects.
