#' Homeostasis concept inventory test-retest dataset
#'
#' @description `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.
