#' Body measurements of 507 physically active individuals.
#'
#' Body girth measurements and skeletal diameter measurements, as well as age,
#' weight, height and gender, are given for 507 physically active individuals -
#' 247 men and 260 women. These data can be used to provide statistics students
#' practice in the art of data analysis. Such analyses range from simple
#' descriptive displays to more complicated multivariate analyses such as
#' multiple regression and discriminant analysis.
