abstract: 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.
