HCItestretest) dataset consists of the responses of 45
students to Homeostasis Concept Inventory (HCI). It contains answers to 20
multiple-choice items, scored items, identifier of test/retest, total
score, gender membership and identifier whether students plan to major in
life sciences. The data are organized so that each pair of subsequent rows
belongs to one student. Students took no courses on homeostasis between the
test and retest.
