#' Swim velocities using different types of swimsuits
#'
#' Data from an experiment comparing maximum swim velocities when swimmers are
#' wearing a wetsuit versus a regular swimsuit.  Paired measurements on the
#' velocities on each of 12 participants. Data includes swimmer's biological sex
#' and indication of whether the swimmer was a triathlete or just a swimmer.
#' These data are also contained in the package Lock5Data
