#' In an experiment, subjects participated in role-playing dialog under various conditions,
#' while researchers monitored voice pitch (Hz).
#' The conditions spanned different scenarios (eg: making an appointment, asking for a favor)
#' and different attitudes to use in the scenario (polite or informal).
#' 
#' @format A data frame with 84 rows and 4 variables. Each row represents a single observation for the given subject.
#' \describe{

#'   \item{attitude}{whether the attitude to use in dialog was polite or informal}
